Why is my bbt still high and AF is here?

I miscarried for the 6th time, which ended last month. I have been taking my bbt to know when O day is coming since we are ttc again. My temp has been high like it is when I get pregnant, but I started what I think is my period on the night of the 19th, which is right on time. My temp is still 98.6 every morning and it's usaully 97.9 the day before I start AF. My period is very lite which is different for me. I have been taking a baby asprin everyday and using progesterone cream everyday until I started bleeding and then I stopped. Can that make my bbt stay high or is something wrong with me. And yes I took a hpt on the 19th cause of my high temps and it was neg:( I go to the Dr's next week, but I can't help but wonder what's wrong with my bbt. I would love any help:) Thanks!

I am one of those women who's bbt stays elevated for a couple of days after af arrives. It may go back down tomorrow. Yes, progesterone supplements can cause it, too. It should be out of your system soon.
