bleeding 3 days after losing virginity

So this past friday I had sex for the first time. I am on the pill and we used a condom and pull out method. There was no bleeding during but the morning after I was spotting. This has gone on for 3 days. It is very light and is starting to make me worry. Is this normal and has this happened to anyone else?

Also my period isn’t for another 15 days. Should i be worried about pregnancy or anything else?
