I'm on day 3 of Af but my bbt hasn't dropped. In fact it's spiked again. Flow seems to be normal but I have some very strange, intense cramps at times. Nothing seems to make it stop. I had a song a few days ago and the dr said I'm. It pregnant. Had anyone ever had their bbt continue to climb during af? Did you find out why? I'm taking clomid but it's never done this before.
