I give up!!!!

Me and my fiancé have been trying for almost a year. With my daughter it only took one month. I'm at the conclusion that he is sterile, and he won't go get checked. At least I was able to give birth to my 7 year old daughter. I've always wanted more, but I guess it wasn't meant. I'm heartbroken, but I have to be grateful for what I've been blessed with.
