K.C.
6 weeks is very early and it's common to not find a heartbeat this early. It doesn't mean anything bad that they couldn't find a heartbeat. This could go either way. I know women who had this happen and went on to have a healthy baby. I also had this happen to me and it resulted in a miscarriage. It really can go either way. I know it's hard to not worry, but you just have to wait it out and try to think positive thoughts. Good luck.
