So, last month on the 20th (a day after my period) my bf and I had sex. When he pulled out, the condom didn’t fully come out (it wasn’t inside me, just sticking out) when he took it out, some of his “liquids” got on the side of my vagina. Should I be worried?? Bc he told me like a million times, that nothing went in me. But my period is late, and my periods are irregular. So I never know.
