Kinda worried today:

So had my first US on Thursday. Healthy 145 heartbeat and I thought I was 8 weeks (based on my last period) but I measured 6 weeks. I also have a subchorionic hemorrhage. Would that be a reason baby isn't growing the way he/she should? Also, if they have a disability will they not grow as fast? Just want to make sure my baby is happy and healthy. 😞
