Period or what?

Charlie Cay • Tue, Jan 29

So I had my period from 23rd-26th this month. It came a week early but was normalish. We had sex on the 27th. Well after having sex I started spotting(bright red). It is now the 29th and I’m still spotting(brown) when I wipe.. I’ve also had sore nipples and some nausea and headache.
