Pp period

I’m 7 weeks pp and after having some wild alone time with daddy the other day I’ve been noticing a light bright red spotting today it’s getting darker and a bit more heavy(not enough to fill a pad) but enough that I have to wear a pantyliner. I think it may be my period coming or maybe we were just to rough I’m not sure but My question is How long did your period last once it came back? I’m so bummed I can’t stand Mother Nature some times😩
