First month on the pill

It's my first month on birth control and about a week ago it was my first time having sex. I knew that I was going to bleed a little after sex and I know spotting will happen a lot when I'm on the pill. just a few days ago I started to bleed and it has been going on for a couple days now like I'm on my period, but I'm supposed to start my period in a week... is this just spotting? Is my birth control messed up? Do you usually get this much blood after sex? It doesn't make sense because I take my pill once a day at the exact same time on the dot! I'm so confused. Someone please help.
