Trying Get Pregnant After Having Gastric Bypass Surgery.

April, 16,2015 I had gastric bypass surgery rny. I had abnormal mistral cycles for 8 months after I would have my period sometimes 15-20 days out of a month. My doctor had me taking serval different pills I even started taking birth control. I would still have abnormal bleeding while I was taking the birth control pills. So I stopped taking everything. The last 4 months my period has been on track. Do you think I will have trouble getting pregnant? Can I take anything over the counter that will help me become pregnant faster? I'm ready to be a mommy!!
