Pregnancy update

Went to the doctor today because I been having cramp feeling in my belly. He doesn't seem to think it's a big deal. I hope he is right! I have never carried to full term with any of my kids so I get really worried when I have alot of pain. Thankfully my children are healthy. I had my 2 boys both come 6 weeks early and my daughter was 3 weeks early. I thought I might be in the high risk category due to this but the doctors haven't said that. I go to a clinic where there are 4 different doctors and they take turns seeing me. I guess it has it's pros and cons but I like it better seeing the same doctor and knowing who will be delivering my baby. I live in a small area and don't want to travel to far for doctor visits on count of having my babies early so I feel limited with my choices.
