I'm really trying not to think negative, but keep having a fear of miscarriage. I never had one I've been having cramping since I found out I was pregnant. My doctor thinks its my uterus stretching back out since it's been almost 6 years since my last pregnancy. my doctor did a quick ultrasound to make sure the baby was in my uterus the heartbeat was seen did not try to listen to it because I'm only 9 weeks. Any advice on not worrying so much about losing the baby
