Doc wants me back in for blood work?

Long story short.. I had a chemical pregnancy last month at 4 weeks.

I have no history of miscarriages or chemicals But this one time.. I’ve had 1 healthy pregnancy with my 1 year old daughter. I’m currently pregnant again 1 month after CP...

Just had blood work 2 times. My hcg is more than doubling every 48 hours. My doc wants me to come back again for blood work just incase..

What’s the point in that? If I miscarry I miscarry.. what’s me getting blood work again going to change anything ?
