Pill effectiveness

Autumn

I know y’all see this kind of post all the time, but I am going to post it anyways. I was on tri-previfem for 1 month. I was then off of the pill for 10 days. (Had to switch to Larissia). I had unprotected sex on the 7th day of the placebo pill and he finished in me twice. I just want to know what the general chances of pregnancy are. Thanks everyone.

This was BEFORE the Larissia was started
