BBT decreasing and pregnant

Monica

I am about 6 weeks pregnant. I have a doc’s appointment on Wednesday, June 5. I wear the Ava bracelet at night to chart my BBT. It seems to be decreasing slowly. Should I be worried? Could this mean a miscarriage? My hormone levels were fine two weeks ago at the doc’s. Am I just being paranoid?

PS: I haven’t been sleeping great. I don’t know if that’s an issue with BBT. But since I wear the bracelet, it usually doesn’t matter that time it registers the temps.
