Hi, I'm 35 Yrs Old, 7 And Half Years Married.

Hi, I'm 35 yrs old, 7 and half years married. I go to my OB for almost 5 months, she is giving me a fertility pills on my 2nd day of menstration for five days, my body response everytime I take it base on my TransV. But not getting pregnant, so she decided to try the Hysterosalpingogram last month, the result is good both uterus are open and no polyps inside, the polyp is only at the cervix. Until now I'm not getting pregnant, is the cervical polyp can block the sperm?
