What is the Follicular Phase?

    Why don't women ovulate on the same-ish day each cycle? And if my follicular cycle is less predictable, then I have to be more cautious of my BBT during the first half of my cycle than the latter luteal phase because that is more consistent, correct?

    The idea that all women ovulate on the same day each cycle is actually a myth! It probably started based on the idea that the average cycle length for women was 28 days, and so dividing that in half puts ovulation at day 14 - however, many women's cycles are longer or shorter than 28 days, and even for those that do have 28 day cycles, it's pretty unlikely that they'll ovulate on day 14 every time. It's not really clear exactly what causes a woman to ovulate on different days each cycle, but that's why it's really important to track your fertility signs each day, so you can know for sure if and when you ovulated.

    As for your BBT, it should consistently stay in a lower range during your follicular phase. So, your temps should be fairly consistent until you ovulate. Once ovulation occurs, it will rise to its higher range, and your temps should stay in the higher range for the rest of your cycle. Some women find that after they confirm the temperature shift (i.e., the temperature shift has been sustained for at least 3 days), they don't feel the need to take their temperatures for the rest of their cycle. This is fine if you've been charting for a while, but if you're new to charting, it's a good idea to take your temperature every day, so you can get the hang of it. Also, if you're trying to get pregnant, taking your temperatures throughout the luteal phase can be helpful - if your temps dip below the coverline during your luteal phase, this could indicate a hormonal imbalance that might be preventing you from getting pregnant. Or, if your temps stay high for more than 18 days after ovulation, then there's a good chance you ARE pregnant!

    Is it normal to have temps jump up and down in the follicular phase?

    Hello!  Thanks for writing in!  It's totally normal to have varying temps during the follicular phase (mine looks like spikes).  What you're looking for is that the temperatures during the follicular phase all cluster lower than the temperatures during the luteal phase (which will also vary, but they will cluster around higher temperatures).  Hope this helps!

    Is it possible to shorten the follicular phase? My LP is usually the same but my FP varies and is long. I have very few dry days. My cycles are 31-39 days.

    Hi Erickmilo, thanks for contacting us!  It's hard to say exactly what might work to regulate your cycle because everyone's lifestyle is different, but often, regulating your cycles and jumpstarting ovulation can be a matter of diet and lifestyle changes. What will work for you depends on a lot of things that factor into your everyday life. Here's an article by Kindara co-founder Kati Bicknell that goes into more detail about some of the ways you can regulate your cycle:

    I hope this helps :) Please feel free to let me know if you have any more questions or need any more help!

    Is having a consistently longer (say 20-25 days) follicular phase resulting in cycles up to 38 days something to be concerned about? Along those lines is a consistently long cycle 37-38 days considered 'irregular' just because it's longer than the average range?

    Hi Jacqueline, thanks for contacting us! Women's bodies vary, and while a 38 day cycle is a little bit out of the normal range it doesn't necessarily mean that something is wrong, especially if your cycles are regular.  As long as you're ovulating regularly and your cycles stay in generally the same range, there's usually nothing to worry about.  Let me know if you have any other questions!
