HCG down then up a little?

I got HCG & Progesterone tested Monday (3w5d) and HCG was 35, Progesterone was 16.

Got HCG tested again two days later (4w) and it was 33.8.

Got HCG and Progesterone tested again two days after that (4w2d) and HCG had gone up to 54 and Progesterone down to 10.4. I haven’t heard from my doctor at all about results, but googling has shown this to not be a good sign at all.

Any one have any similar stories? I’ve had two MCs in the last year and I’m going to go ahead and expect that this will end the same way.
