hello, im 24, and i wanna know why i sometimes get a fishy odor during intercourse?Ive been pregnant three times, and during two of my pregnancies, i had been diagnosed with having strep b. ive had a fishy odor before, and after pap smears, ive never been diagnosed as having a BV. I was told that I had a yeast infection during my second pregnancy. Also, if im not mistaken, I believe, i heard on a tv show one time that, sometimes during intercourse the cervix could be getting hit causing a fishy odor during intercourse, but like i said i could have completely misunderstood that. Any advice?
