Molar pregnancy?

I’m a little nervous because my HCG levels quadrupled over 48 hours. I’ll be 4 weeks tomorrow. I looked up if that’s normal and I ran into something that said if your levels are rising too quickly it can mean a molar pregnancy? I’m stressing myself out something horrible. Is this something that’s super rare? I’ve had two other babies and no issues at all with them. I’ve also never had infertility issues either. Idk why I’m stressing so much. I never had my levels checked with my other pregnancies… I guess every Dr. Is different. Seeing the numbers make me overthink it all.

My first blood draw was 37 and the next it was 146. What do you guys think?
