Wow what a roller coaster for you
I have everything crossed you just have slow rising hcg and it turns out to be a healthy lil bean in there! Can you get an u/s anytime soon?
I would also recommend an ultrasound, this way you and your doctor can see for sure what's going on in there in case it's ectopic and you can do something about it right away. Seems like that would be the safest option as opposed to just stopping the progesterone, just in case baby is just now really snuggling in and you end up with a healthy viable pregnancy.
I'm really sorry you're going through this Maureen!
