I’ve been taking a 28 day birth control pill for months. I skipped for 2 months because I didn’t go in for a refill. My last period was on may 16th through the 20th. I started back on the pill on June 5th. And had sex on that day. I know you’re supposed to wait up to 5 days before engaging in unprotected sex but it was the 19th day of my cycle... my period is always right on time. Without the birth control pill my period should have started on the 11th of June but with it it was supposed to start 2 days ago. Either way it’s late. I’m worried I may be pregnant.

I was wondering what the possibility of me being pregnant is if:

I had sex using the withdrawal method

on the night I started my pill

On the 18th day of my original period cycle

*im cramping like I always do before my periods about to start* but I have been for days
