I can not believe it

I can not believe it!!!! My boyfriend, 31 years old, found out a long time ago that he has varicoceles, and was told that it's severe enough that it would leave him infertile permanently if he didn't get it fixed. Well, he never got it fixed, never got anyone else pregnant having unprotected sex. We never used any protection because we completely trust that he was infertile based on the history. In disbelief, I was pregnant this past February , and had a mc in late April. We've been ttc every since but with low hope that there'd be any success. Guess what!!! Last week I had a strong feeling I must be pregnant (without having any symptoms), then today 7/19/15 five days before my period is due, I decided to take a hpt after been having really bad indigestion for the past 3 days, and I got a BFP!!!!!! This is crazy!!! I'm praying that this one will stick around!
