My baby s 1 Yr old, I had c section and from last 4months my periods r irregular.. And often I get some stomach pain.. Now I consulted a doc and found that there s some muscle near my bellybutton and this was named hernia, she said a surgery has to be done if I have severe pain n future... Due this stomach pain we didn't have sex from past 1 Yr.. Will this surgery affect from getting pregnant 2nd time, and also is this a major one?
