Normal hcg for almost 5 weeks?

Holly

With my first pregnancy I had very high HCG levels... Like 21,000 or something crazy.

I had my hcg check w my progesterone on tuesday and it was 273 I was exactly 4 weeks. I got it checked again on Thursday and it was like 600 something. I know it doubled in the 48 hours but is that low for 4-5 weeks? I keep reading different things.

☹️Trying not to worry.
