Help me please!

PLEASE HELP PLEASE HELP I have PCOS. i was on birth control but in August i stopped taking them bc they made me gain weight. I haven’t had my period since August. But In December i lost my virginity and i started taking the pills again like every other day. And 7 days ago i had raw sex but he didn’t even cum in me or cum at all. Now my “period” came out of nowhere. And it’s very light. Could i be pregnant ? Or am i crazy?
