Just wanted to let everyone know my experience so they don't get their hopes up like I did if the same thing happens to them. I was on 50mg of clomid for my first month, and also had taken provera earlier to induce my af (before Clomid). I stopped getting af on my own, so I expected to have to take provera again, as soon as I was sure I wasn't pregnant. About 7dpo I started to get REALLY depressed, crying a lot (not normal for me) and by 14dpo my bbt still hadn't dropped below the coverline. I have been meticulous about taking my bbt, and I read that if you go 18 days with bbt above the coverline, you have a 99% chance of being pregnant. I spoke to my OB and he said he didn't want to get my hopes up, but the depression sounded like my body was producing new hormones, and the bbt supported it. I had been getting cramps all month long, so I didn't think anything of the ones I was getting at 14dpo, because I had them all along. Turns out at 15dpo af came in FULL force! Apparently, the depression was just PMS - but the good news is I got af w/o using the provera. No one could tell me if you had irregular af if your bbt still dropped after 10dpo, so I thought I'd let those w/irreg af know that it can stay high and yes, you can still NOT be pregnant. :o(
