Worried - Yeast Infection, Cervicitis?

TMI - So 2 days ago my boyfriend and I had sex like usual, except we didn’t finish because when we were switching positions, there was blood on him and my period isn’t suppose to come for a week. I’ve been having yellowish crusty discharge in my panties lately too. Nothing hurt during sex, so I’m not sure what happened. I now have brown type discharge instead of the yellow. I don’t know what’s going on. I’m 20 and I’ve never been to the gyno because my family is extremely religious and my mom would kill me if I tried to go... advice ladies?😓
