SOMEBODY HELP!! 🤦🏽‍♂️

Ok so I lose my virginity a few weeks ago to my boyfriend and I'm 21 , I took a birth control pill right after sex too. Finally I got my period but my period seems weird like I'm not bleeding heavy it's real light than usual and it has a weird smell and I've been spotting brown then it goes back red .... Is this normal ??? And should I douche ?? Because I'm scared and have no clue because I just started having sex and this is complicated !
