birth control

Okay guys I need advice and help. So I'm on birth control and my eve app is usually regular when I start my period but I missed it and it wasn't synced with my placebo week so I moved onto the next pack until I started. Well I missed a day so I double up the next day then I missed that next day and doubled up again... during the time I missed to take my pill I had sex and my boyfriend came inside of me. I'm 6 days late on my period now but I've had no pregnancy symptoms really... I was going to test to make sure but I'm asking anyone if they know that because I missed and still doubled up if there was a chance I could've gotten pregnant?
