I'm 6 weeks!!! I have a doctors appointment on May 6! I'm nervous! After losing my son I'm so worried about almost everything.. This pregnancy I'm not having many symptoms.. Sometimes I get sick to my stomach, a little cramping (but normal) but my boobs aren't terribly sore, but I am extra bitch (a little more than usual lol) is this normal? I guess I'm so scared to go to the doctor and they can't find a heart beat or something!! (One of my worst nightmares) after what I went through with my son 💔
