Pregnancy

me and my boyfriend he's 24 I'm 20 & we been trying to get pregnant over 6 months now.. & it's getting ready frustrating for me. He has low sperm count and before he had erectile dysfunction. I'm at the point I'm tired of trying we both have job so if your going to be negative I don't want to hear. We bought fertilaid today & tried Preseed and nothing I very annoyed I want to be a parent and it's making me VERY depressed.
