I had a tubal 3 months after my 7 year old was born. Since then i have had cervical cancer removed twice. But recently, my husband and I have both been feeling like something was missing and realized that with three girls wanted a to try for a boy. I have taken those prenatal vitamins that are otc that you can taken to increase your chances of getting pregnant not to mention help through a pregnancy. Instead of getting pregnant, I have my period twice a month if I don't just stay on it all month long. It's not easy to get pregnant if you can't stay off of your period long enough to try. Can someone tell me what I can do to increase my chances or at least show some insight as to what might be wrong please? :'(
