First post ever!

Hello all, I normally never post on here but I’m just searching to see if anyone has ever been in a similar situation....I’ve had 3 miscarriages. 2 about 3 years ago, most recent one i had was May 2019. All at around 6 weeks. I currently found out i was pregnant again after this past miscarriage and got some labs done this past Thursday. My progesterone is at a 47.40 and HCG Is at 72,168!!! Yes i have been taking 200 mg everyday of progesterone (hence my progesterone level is very high) since my OB stated my progesterone was low the past pregnancy but it could have been due to the fact that the pregnancy was already failing. I called my Ob today and she can not get me in until next Tuesday, she is predicting I’m around 6 weeks since my last “period” was mid July but it was very light brown spotting.

I’m just really concern about my HCG levels, she stated that it’s very high. Should I be concerned? I’ve been doing some research and I’m just freaking myself out....and no my husband nor do I have a history of twins in the family.
