My temp went down AGAIN by another tenth of a degree. I don't know what's going on but it sure is discouraging. My temps haven't even hit 98 degrees once since ovulation. I can't see how that's not a bad sign.
By the way, I ended up getting a new BBT thermometer yesterday, because I convinced myself that my old one wasn't working properly. However, upon doing a side-by-side test (literally - one on each side of my tongue), I discovered that both read pretty much the same, which means that my old thermometer was indeed correct and I just wasted $25.
I heard back from my doctor's secretary this morning. She said that my TSH levels are not a problem, as the elevation is so small and the "Free T4" level is well within normal range. It's a relief, but I want to talk to my doctor about it anyway, and while I'm at it, I'll ask her about my wonky temps.
Today is 7 DPO and implantation could be taking place anytime now. Despite my discouragement, I am still hopeful.
