HCG not going down

Shelby

Hello, we had a chemical pregnancy with our first FET back in Nov, the highest my HCG went was 129 and then it started to slowly go down. Fast forward two weeks later it’s still only gone down to 85. RE wants to test again next week but hasn’t told me anything else. I’m worried about ectopic or molar (can you even have a molar with PGS embryos?). Has anyone else experienced this and had to have medical or surgical removal? Thanks for any advice or opinions!
