HCG levels

Kr

Ok.. I think I’ve lost my mind. This is my first pregnancy and I’ve kicked it off with a UTI and pinched nerve. My OBGYN wasn’t super impressed with my Hcg levels last week (I’m 5 weeks tomorrow). They’ve had me test three times and I’ve doubled each time. At 4w2d I was at 309. I know it’s in range, but it seems low. Soooo despite having an appointment at their office Friday for more blood work, I went to my workplace’s clinic for an extra test. Am I crazy? I just want things to be ok!
