HCG levels

Kylie • FTM to a baby boy 1/28/19💗

My HCG levels on Friday were 514 and on Monday they were 1622. My progesterone level is 13.6. I’m 4 weeks and 6 days according to this app. Does everything sound okay? I’ve never miscarried but so many stories I’ve heard make me nervous. I’m trying to relax but just can’t seem to stop thinking about it 😕
