Spotting after sex?!?

So last week I started a new packet of birthcontrol in order to skip my period because I was in a wedding! And last night my SO and I had amazing sex but I noticed was a bleeding a little afterwards. Is that normal? The intercourse was a bit rougher and deeper than usual so I wasn’t sure if that caused the spotting. Or if me skipping my period also caused the spotting? I’m still having a little bit of a blood in my discharge and I just want to make sure that it’s normal?!
