Plan b and birth control

This is kinda tmi !!! Sorry!

But what are the chances I’m pregnant or could become pregnant if my bf pulled out and if I only have one ovary and one tube? I got my left side removed in November and was on birth control ever since. I just came off last week. Had my withdrawal bleed. Then my bf did withdrawal today, all of it came out on his hand. Sorry for the images.

I highly doubt I could become pregnant because we rarely have sex especially with no protection. And especially since I only have one side (right ovary and right tube) I’m thinking of testing in two weeks then getting back on birth control.

I took plan B this morning at 7am... am I ok?
