Yes Please,i Did Fibroid Surgery In 2008 Nd After D

Yes please,i did fibroid surgery in 2008 nd after d surgery in August my periods came d following month but not completed d days nd not heavy as well, since den it has not been coming till date. Now am married nd need to have my own children, though i didn't go for any test since then because i was told t exercise patient that it happens sometimes. But i discovered that if we have sex with my partner d sperm is watery nd it will be coming out of my vagina,so am confused nd scared. What could be the cause and is it possible to have my period back?
