Me and my boyfriend had unprotected sex. During, he pulled out for a moment then went back in. We continued for just a moment and i had happened to feel something on the sheets. It seems that he had c*m and didn't know. After we found out this happened, he pulled out and put a spermicidal condom on his hand and rubbed it along my inside and walls. Then, just to be safe, cleaned me with soap and water along my walls and inside too. I can't remember when the last time i had my period was but i do know im due either this week or next and im usually 28 days. Are we at a lower chance by taking those precautions? (ps sorry for the graphic language)
