LJ, the EXACT same thing happened to me the week before

I was getting +HPT since the thursday, got a HCG of 76 on Sat, my clinic told me to be cautious, i had already been bleeding for about 14 hours. I had a follow up bloods on the Monday and my HCG was down to 18.

They dropped extremely quickly.

Did they happen to tell you what your progesterone was?
