Missed a lot of BC pills...

Before anyone starts saying negative rude comments let me just say I have had a lot going on this month and my mind on a lot of things... I am usually very good at taking my pill on time everyday specially since I have an alarm but this month has been different...

I completely forgot to start my new pack the first 6 days.... then went two days of taking them then bam missed two more back to back... finally got back on track and have been taking them since but a few days were late.... iv had unprotected sex with my bf 4 different days....

My period is scheduled to start on the 28...

I know my chances are high that I could be pregnant but because I didn’t have sex in those first 6 days I was suppose to start my pack doesn’t my chances go down a lot?
