    Where is the corpus lutetium located? Does it get shed with the endometrium (that's my period blood, correct?)?

    Thanks for your questions! The corpus luteum is located on the ovary - it's the tissue that's left after an egg bursts through the ovary at ovulation. At the end of your luteal phase, the corpus luteum doesn't get shed with the endometrium (correct, the endometrium is what is shed when you get your menstrual period) but rather disintegrates. This means your body's progesterone production gets shut off, and you get your period.

    If implantation has occurred, then the corpus luteum will last for about 10 weeks post-ovulation, and will continue to secrete progesterone during that time to support the endometrium. After about 10 weeks, the placenta takes over progesterone production, and the corpus luteum disintegrates.

    What are options for treatment for low progesterone? Are there dietary changes you can make?

    Hi there,

    it is possible to raise your progesterone levels naturally. Here's an article with some useful information on how to do that: http://holistichormonalhealth.com/how-to-identify-low-progesterone-and-raise-low-levels-naturally/

    You can also use progesterone creams or supplements, which are available in most drugstores. However you may want to check with your doctor before opting to use these.

    Hi there,

    Implantation generally takes place 6-12 days after ovulation.

    I am 38 and have been trying to conceive since Dec. 2013. I am currently on day 19 of my luteal phase. Could 19 days be within the normal range of luteal phases? Since I have been charting with Kindra, my cycles have varied between 25 to 32 days long. My luteal phases have been as long as 17-18 days in the past, but some months I charted as low as 12 days. Is that a sign of infertility or something else I should ask my doctor about? My husband and I want to get pregnant, so I'm a little concerned about these inconsistencies in my cycles. Thanks for any thoughts or suggestions you might have.

    Hey there,

    A luteal phase of more than 18 days is generally a good indication that you're pregnant - you may want to take a test :)

    Just a note to clarify...pregnancy does not start at implantation, pregnancy started when the sperm and egg fertilized. That's where we get all our DNA - during the fertilized time.

    Hi squiroa, When you mark a temperature shift, the app will count the days from your temperature shift until the end of your cycle (i.e., the length of the luteal phase). The app recognizes this as your luteal phase. You can view your luteal phase data as well as your other data at our user web portal. 

    lynnheeren - There's a lot of debate over whether pregnancy starts at fertilization or implantation, but the medical community at large maintains that pregnancy starts at implantation - which is why we said that above. It's a bit of a gray area, however.

    My luteal phase is 9 days long. I am seventeen. Everything else is pretty normal. Does this mean that I won't be able to have kids later in life?

    If i got my period 10 days after my peak day the meant that i got it correct? (The peak day)

    Hey Sophie! A short luteal phase may make it more difficult for a woman to get pregnant, but not to worry! There are lots of ways to lengthen the luteal phase, naturally and medically. So, having a short luteal phase now shouldn't interfere with your ability to get pregnant down the road. This article has some suggestions: https://kindara.zendesk.com/entries/23572611-Remedies-for-Luteal-Phase-Defects- 

    Maria - The peak day is the last day of fertile (i.e., wet) cervical fluid before it starts to dry up again for the rest of your cycle. There's no guarantee that it will occur on any specific cycle day. So while it's possible that the day you mentioned was your peak day, without more information it's not possible to say.

    If you're trying to avoid pregnancy, is it safe to have unprotected sex during your luteal phase? Should you avoid the few days in the beginning or are you safe the entire time?

    Last month my LP was 13 days.  This month (today) it is already 15 days DPO.  Can your LP differ by much every month or does it vary by 1 or 2 days.  I am unsure to the days of my LP.  I also read that having a short LP is not good, what about a very long LP.  Is a LP of 18 days the norm? I don't know if I should test or wait

    Is it possible to have an LP longer than 18 days and NOT be pregnant?

    Hi Camsand - in order to avoid pregnancy with the Fertility Awareness Method, you'll need to follow a set of rules that inform you when it's safe to have unprotected sex.  These rules will let you know when it's safe to have sex during the luteal phase.  You can read more about this here:

    https://kindara.zendesk.com/entries/22043400-The-4-rules-of-using-the-Fertility-Awareness-Method-as-birth-control-explained

     

    Hi Marcel, most women's luteal phases stay fairly consistent between cycles, but variation between 1-2 days is totally normal and very common.  Most luteal phases are between 10 and 16 days long.  A luteal phase of 18 days or longer generally indicates that you're pregnant.

     

    sjacob, it's possible, but quite unlikely to have a luteal phase longer than 18 days and not be pregnant.  If you're not sure, a pregnancy test may help you get a little more information about what's going on with your body!  I hope this helps.  Let me know if you have any other questions :)

    After my miscarriage and D&C in September my cycle has changed. We started TTC again in November, however, with no luck so far. Now that I am tracking my ovulation it seems that twice I have started spotting between 7 and 10 dpo. But my full period is coming about every 32 days. When we conceived in July I had just come off of birth control pill. I have a two part question: could I have low progesterone? And should I consider the early spotting the end of my luteal phase? Right now I'm experiencing my two week wait I am now 6dpo. However I my test kit indicated that I ovulated day 19 this month whereas every other month it's been day 14. This is exciting did he bc I think maybe my ovulation and cycle may finally be back on track.

    Hi Cassie, it is possible that your spotting is a symptom of low progesterone, but spotting itself at the end of your luteal phase is actually quite common and isn't necessarily anything to worry about.  However, if you're concerned and if the spotting doesn't clear up in another cycle or two, you may want to get it checked out by a doctor for an assessment.  As for your second question, you should consider the first day of any RED menstrual bleeding (not spotting) as the first day of your next period.  Hope this helps :)

    I've had luteal phases ranging from 9 days to 16 days over the past year of charting. Does that indicate a problem? I take temps every day around the same time.

    Hi Sara, it's a little unusual to have luteal phases that vary that much, and luteal phases that are shorter than 10 days may indicate a progesterone deficiency.  You may want to check with a healthcare practitioner about your symptoms to see if they can diagnose any kind of medical problem that's causing your luteal phase variation.

    Hi my luteal phase was 13 days last month (my first chart). My chart now is already 16th day of my luteal phase and temp is still high. Could this be caused by stress.

    Sam

    Hi Mosquitogirl8, Stress absolutely can delay ovulation and wreak havoc on your cycle in other ways.  Also, although your luteal phase is generally the same, there can be a small variation from cycle to cycle.  That being said, when your luteal phase looks like it's extending longer than normal and your temperatures don't drop as you expect them to, this can also be a sign of conception, it all depends on when you may have timed intercourse around your ovulation day whether this is possible.  Good luck!

    Is it common to have CF during the literal phase?

  • Avatar
    Sam

    Hi lmourtgos, Yes, lots of women continue to have CF during the luteal phase.  That being said, past a certain point in the cycle (Peak +4 and Temp Shift +3) it is no longer considered fertile cervical fluid, it's just normal cervical fluid.  Hope this helps!

    After coming off the pill 8 months ago I've had several cycles with a super long luteal phase 22 days on one and 24 on the other with a normal cycle in between. No positive pregnancy tests. Is this a sign something is wrong or just my body getting used to being off the pill?

  • Avatar
    Lauren

    Hi Arielle, thanks for contacting us!  Hm, it is possible that your body is simply adjusting to being off the pill, but it's also possible that you may be experiencing ovarian cysts (which can sometimes mimic pregnancy by having a long luteal phase).  Ovarian cysts are usually benign and resolve on their own, so this isn't really anything to worry about!  If your cycles continue to be irregular or have unusually long luteal phases, or if you feel any pain or other symptoms, it's probably best to be assessed by a doctor (and bring your charts along when you go in for diagnosis - this can be really helpful!)

    I hope that helps. Let me know if you have any questions about this.

    Hi, my luteal phase is 7-9 days long. I am TTC next cycle, should I discuss this with my gyn? I already did a pre-pregnancy check up and she assured me everything looked fine, but she didn't mention anything regarding luteal phase.

    Hi Ria, thanks for contacting us!  Hm, it's generally believed that a luteal phase of at least 10 days is necessary to sustain a fertilized egg.  If your luteal phases have been shorter than 10 days, I'd recommend checking with your doctor for some advice about the problem.  Good luck!
