Charting To Avoid Pregnancy

    In number 2. you say that the "accuracy and effectiveness of each method varies," how do I know that tracking my BBT and cervical fluid are the best methods for me?

    Hey hacw,

    In terms of methods to detect the fertile window, tracking your BBT and cervical fluid is accurate, affordable, and accessible. Blood and saliva tests can be useful for determining your hormone levels, but they won't be helpful for pinpointing the fertile window as it occurs, as you'll need to wait on a lab for the results. Other methods such as ultrasound scans can detect ovulation; but again, this isn't a very cost-effective or convenient method! Urine testing (with ovulation predictor kits, or OPKs) can also be very useful for determining when you're becoming fertile - however OPKs only tell you when you're approaching ovulation, not when you have ovulated. Only tracking your temperatures and cervical fluid can tell you that :) Ultimately, whether fertility charting is the best method for you personally is up to you - but I encourage you to continue reading about it on our Knowledge Base, and let me know if you have any other questions!

    My period is 6 days late today. It isn't uncommon for it to be 1-2 days late each month. I've taken 3 tests, me last night=negative one this morning with first morning urine and it was odd. The faintest line I've ever seen, so light in fact that my husband says there was not a line at all- but I saw one. I went out and bought another test and took it a few hours later, and it was negative. I've been drinking a lot of water lately and I wonder if it could dilute the hormone. I've had sore breasts the last week which usually means period is coming. I'll take another in the morning, but I'm curious to hear what y'all think
