i think better to see the doctor about the menstrual cramping you are having, bcoz its related to your pregnancy. Good luck
Certainly worth checking out. A pregnancy test could be positive for a while after a miscarriage. I don't know facts, but now that you are pregnant, unless your uterus was affected by your situation you would be in the same risk group as everyone else. If your doctor said you would have a slim chance at getting pregnant and *maintaining* a pregnancy that would be different.
Congratulations on overcoming the odds. Definitely see someone to be sure what is going on.
