no, my friend had a stomach ulser all through her pregnancy and she now has a healthy 3 month baby girl
Well, I don't think that it will lower your chances of getting pregnant, the only thing I see that may cause a problem is if you were to get pregnant with an actively bleeding ulcer you would be anemic, but if you have an actively bleeding ulcer, you need medical attention as soon as possible to avoid any serious problems. I am currently 16+ weeks pregnant and I have horrible stomach and intestinal problems, and the baby is justs fine. You should see the doctor to get this taken care of asap either way though. Good luck!
