Hi everyone! Last Wednesday I had an ultrasound with 6 weeks+6days. There was a hearbeat, but my embryo was measuring 5 days behind... I'm very concerned about it because I know exactly when my ovulation was, since I feel pain every cicle. In addition, I got a positive test 10 days after. So, I know that it's not a late ovulation or a late implantation. How worried should I be?
