I'm a first time mom so I have no idea what is happening to me but my obgyn doesn't seem concerned but I just can't shake the feeling that something is wrong...Firstly, the pregnancy test came back positive at three weeks. At three weeks and a few days my hcg was already at 420! It didn't double (734) but my doctor seemed unconcerned. I've been having mild pain and cramps in my right side and I keep spotting on and off.I'm 5 weeks today and my doctor refuses to do an ultrasound before 7 weeks. I guess my question for other moms is: Do your doctors do ultrasounds early? Why might mine not do it before 7 weeks? My husband has basically written the baby off as a miscarriage but I'm just concerned it's ectopic and is going to kill me. Any advice?
