Unable to conceive...

My fiance and I started dating in April of 2015; and not long after we started trying to get pregnant. It hasn't happened for me yet. I went to the doctor last year in January for the dye test and level check, they said everything looked good. I wanted my gut to get his sperm checked, but he had issues with his insurance company and never went to get tested.

Well we split up in April this year, reconnected and got back together in September. The issue is that he was seeing someone else during our split, and she wound up getting pregnant. He can only assume its his, assuming she didn't cheat. She isn't due until March and he will be getting a paternity test done.

I'm so scared that the issue with conceiving is now mine. If this child is really his, it might break my heart to know that I may never have children of my own. He has 3 others, and 1 on the way now...there is no issue with me being there and helping him raise his children...

I just dont know where to go from here.

What is my next step to finding out if the issue is really mine? I'm 33 now, not getting any younger and the feeling of wanting a baby of my own is so powerful...
