I just start my 3rd month of birthcontrol and I let my boyfriend cum inside me for the first time last week and then a second time 2 days ago just yesterday I see light pink spotting and then today it’s a Little bit more than spotting and it’s red could it be my period early or something else now Ik that birthcontrol prevents you from ovulating but I’m a person that overthinks is it possible that I could pregnant also I am suppose to get my period in a week or two could it just be early ? And sorry but this it what I saw today

Pls help

Am i overthinking ?
