Missing 3 pills

Okay, I hate to be one of those people but I’m very nervous.

I’ve been on the pill for 3 months now, I took 2 of my inactive pills when I started my period this month and for some reason I thought I took the inactive pills for my whole period, so I’ve missed Saturday. I finished my period Sunday morning and had unprotected sex Monday night, stupid I know, now it’s Tuesday and I’m about to take my pill after not taking 3 proper pills.

I know there’s a chance of pregnancy now I just need some help, or advice or some kind of reassurance...

I already feel like an absolute idiot, I just need some big sister words ladies

Thanks 💕
