I'm 6 weeks and have had some spotting. No cramping and have already been to the doctor a few times because I'm high risk. I'm 33 and my only child is 13 so this is all new. My hcg levels are increasing slowly and the sac is growing but not as quickly as most pregnancies. My doctor hasn't lost hope but I'm not going to be seen again til the 30th and my mind won't stop. Has anyone had a similar experience with a successful pregnancy?
