Abnormally High HCG?

Elizabeth

I’m currently 4 weeks pregnant. Three days ago my HCG was 306...today it’s 1222. I know the HCG is supposed to double every 2ish days, but the number quadrupled! According to my textbook, the high side for 4 week hcg is usually only about 500. I made the mistake of googling high hcg levels and learned about molar pregnancies...and of course now I’m scared. I don’t have any spotting, bleeding, abnormal pressure, etc. Has anyone else had really high hcg levels this early on? Thanks!
