So it sounds like you were definitely unprotected and you should have used back up contraceptives or you probably should’ve taken a plan b as you haven’t been taking it for a full 7 days to be protected again. Take a test in 2-3 weeks (3 weeks is more accurate) and if you can’t remember to take your pill you should switch to another form of birth control ie the shot, the patch, the arm implant, the iud or the ring
