conceiving issues

So we've been trying to conceive for a few months now. My fiancé was on testosterone shots and now is on a drug to help him produce naturally. So realistically he has no drive to actually have sex. So most times it feels like a chore. Doctor had him go to fertility doctor to be sure everything was doing what it was supposed to! And by golly it is!! But why does it seem like it's not working!? Ugh , this is killing me not getting pregnant yet! I'm considering I could be the problem but don't want to jump there just yet. Wondering if we should keep trying awhile longer before I get checked out?! Anyone got any ideas
