as far as a smell and discharge after your period, It is just left over from the end of the cycle and the vag's way of cleaning out. I wouldnt be worried.
Do you practice safe sex? I would get tested for those "pimples". What do the pimples look like exactly? and the foul smell may mean an infection, I would also get cultures.
Sumtime I get like little pimples on da outside of my vagina but they never hurt or itch. They don't feel like nuthin wat is dat do I need 2 stop shaving wit a razor. An I shave like every week. Also few days after my period my discharge will have this very foul smelll but not like fish jus an weird odor can u help me cuz my mama sayz itz normal
It could be infection like BV. It usually has a strong fishy odor that doesn't go away even after bathing. Plus the odor is stronger durning your period and after sex.
