brown/clear discharge

I had sex yesterday he didn't cum in me but we are new to the sex life so we don't know if pre-cum can get you pregnant but he didn't think he had pre-cum but anyways I'm having brown/clear discharge and he also might have popped my cherry because this showed up right after we did it so can I get some advice and help on this topic please???(it was unprotected and I'm suppose to start around the 15th this month)
