I've Been Married For Seven Years Still I Have Not

I've been married for seven years still I have not got pregnant not even once I am now 26 years old my husband had vareez surgery six years ago for two testicles I've seen so many drs two said I've got policistic ovaries others said I have the shape of policistic ovary but my ovaries are healthy still our infertility remained unexplained I used prumolute for about 15 days twice per day each time one pills or little more then I stopped using it since my period became light and didn't stop them after some time I got my next period this is now my second month but my period has delayed for about twelve days ... I haven't done any pregnancy test cause I am fead up of negative results all those past years .... Is there's any chance that I am pregnant .... Dose prumolute improves my chances to get pregnant after unexplained infertility
