My period was due Feb. 2nd. By the 7th it still hadn’t showed so I took a test. Positive! I’ve had two previous miscarriages so I went to the clinic and had my hcg checked. It went from 145 to 421 in 64 hours. I had it checked again and it went from 421 to 726 in 47 hours. I’m really worried this is super low for how far along I’m supposed to be (6 weeks 1 day today Feb. 14). I have an ultrasound scheduled for Tuesday when I’m supposed to be 6 weeks 3 days, but I’m not sure I’m actually that far along. I usually feel when I’m ovulating but I didn’t this month and we didn’t have sex during glows predicted fertile period. We had sex the 8th, 9th, and the 24th with glow predicting ovulation around the 22nd. Should I be worried???
