I think only a OBGYN or a specialist can analyze how good the sperm is for natural conception, so is everything clear from your end, i beleive so, good luck anyway.
You may want to ask you RE if IUI will help you ttc. Good luck.
I don't think I would not let it stop me from continuing to try for a baby. you may need fertility help from the drs but still there is no reason to stop trying.
