Plan B?

Alright y’all I need your help. Should I take plan B?

I just took it recently (within last 6 months) because I was an idiot and had drunk unprotected sex and used pullout method, but it was right at ovulation. I was on nexplanon under the impression that it no longer worked, being in for 4 years and supposed to be removed at the 3 year mark.

We used a condom last night (and since then). Condom fell off inside me, I fished it out with minimal semen dripping to the opening of my vagina. I’m not sure how much/if any went inside me. I’m 5 days from my expected period. I had my nexplanon removed Tuesday and the nurse informed me that it actually still works most of the time until after 4 years. Either way, it’s not in there now so condoms are the only form of birth control.

Should I take plan B? I don’t want to because it’s not good for you and I don’t think it’s necessary, but he’s really pushing for it.
