Help?

Me and my boyfriend had sex 10 days ago , which was a day after I got off my period. He pulled out , but he pulled out during well (tmi) while in this process we were gonna change positions and I saw he was ejaculating while we were moving around , WELL today I felt a rush of liquid ooze out & it was brown cervical mucus? I know I never ovulate and have brown mucus what could this be?
