First I would test your fertility if you have not had luck let. And she should too. Some guys can get their girl pregnant even while on cycle. That said, your best bet is to stay off gear until you make it happen. If you find that your sperm count is not high enough, I would start clomid at 50mg ED and add 1000iu HCG every 3 days. Then after a couple weeks, decrease the HCG to 500iu every 3 days.
