My friend wanted to know it was ok if u had unprotected on period?

From my opinion I think it's not cool to do so .. She was kinda worried that she did it while on her period.. Could you please be supportive and give honest answers... Plz no immature ppl .... If this isn't a question you don't want to answer o suggest you keep your bullshit thoughts to yourself!!! And others thanks for being concerned and supportive... Thankx<3
