Is it normal that...

Is it normal that I got sorta got my period and put there's barely any blood except when I pee (I don't use tampons only pads) but it hurts way more than usual. Idk if this will help  my boyfriend came inside of me 3 days before my period and a day before it started. Idk is this normal or am I just over reacting because I've heard of women still get pregnant and they have their period.
