Bbt drop after bfp

Libby • 🧡

Anyone have their bbt drop about a 6 days after getting a bfp?? I’m nervous this means my progesterone levels are dropping .. I thought it was supposed to stay elevated through the first trimester.. I know most probably stop taking it after they get a bfp but I continued just to see and it was reassuring every morning when it was still high until this morning 😞
