Had a period, lasted 5 days. 4-5 days later I spotted pink discharge. Last night I spotted what appeared to be a mucus like discharge (white/tint yellow), no smell and hell no I don’t have a std. Just wondering if there’s a chance or if that could’ve been my last period. I did have sex while on my period btw! Also, I do know you can be pregnant while on your period because my mom had hers for 4 months while pregnant.
