I'm new here and have a question I hope you can help me with. My husband and I started trying to get pregnant last month. I've been using a NFP chart to determine my fertile days, etc. For the last three months (since I started taking Vitex and drinking red clover tea to boost my fertility), my cycle has been 26 days and AF always arrived the day my BBT dropped below 98.0. I'm on day 30 of my cycle now. My BBT dropped yesterday, but no AF. I've been mildly crampy for several days and assumed, disappointedly, that I was simply premenstrual. Usually my breasts are sore from the time I ovulate until AF. They aren't sore at all this time, though. And, as I said, still no AF. I don't know what to think.
My understanding is that once you're pregnant, your BBT stays high and does not drop.
