So I'm 17, I got my period a few weeks after my 14th birthday. To this day it's always been irregular so that sucks cause I never know when I'm going to get it. Ive had sex with 3 different guys. Used condoms and everything. I'm not on birth control, never have been. When I'm on my period, the blood smells REALLY fishy. When I'm not on my period my discharge smells fine, but my period smells super fishy. Is this normal??
