Help? Am I safe?

So I had sex on the tenth of November and I keep asking because I can’t get any help with it. I had the bleeding/spotting for the first time in months because of my bc throwing my cycle off. My bc wasn’t affective when I had sex. (He finished inside of me). I feel like a have symptoms but ofc I feel like it’s just because I’m worried. Any help? It was a very light period for the days I had it. But some days it was heavy enough to soak my underwear.
