So this is my 4th pregnancy. And I have no babies to show for it quite yet. I had an ultrasound done on Monday, which showed a sac, but no baby. According to my last period I was 6 weeks on the day. My other 3 pregnancies I never got to see a sac. I had 2 early ectopics, and 1 miscarriage at 6 weeks. So seeing a sac is progress but I’m also so worried! My hcg has been going up, my first was 3300, then 6800, now up to 20000 as of Monday. So my question is, is this normal? Do I just need to be patient and wait?
