Doctors appointments

So the app is saying that I’m 5 weeks and 5 days today with baby #1. I have already been to my OB twice last week for blood work. She told me she needed to make sure my hCG levels were rising, which I understand, but now she wanted me to come in again this week for more blood work to check my levels again. I was told there was a good rise between the first 2 times, which made me feel better. I’ve only had one sonogram and it just feels a little strange to have blood work every week.

Maybe I’m just nervous about possible issues with my PCOS or I’m over reacting because I’m unsure of the process. Anyone else going though this?
