HCG levels???

This is my 6th pregnancy, I’ve had 5 losses very early.

So far they caught, low progesterone, my thyroid levels were slightly high.

I’ve already started progesterone and synthroid.

I had a little spotting around 11-12 DPO. Very light cramping. Some normal symptoms.

My progesterone has gone way up! (Rechecked two days after)

But I’m really worried about my HCG.

It’s doubling under 48 hours.

My fertility specialist said he’s seen low numbers being perfectly viable. I’m just. So freaking anxious.
