Fertility issues.

Da

My boyfriend and I having been officially trying for a baby for about 6 months or so... We have been together for 2 years and in those two years we have never used protection. He has never pulled out either. I already have a 4 year old from my first marriage, but i know now that I have gained weight my period has become irregular again. I gain 35lbs. I missed my period last month too. We have always wondered if he has problems with his little swimmers. His first marriage of five years was a bust in the baby department. He is 33 and doesn't have any children. But today he went to go see his doctor about it. I'm nervous. I hope there isn't any issues. This is something new to us, I don't know what to expect.
