Plan B and how it works

I know I’ve been posting about taking this Plan B already I’m sorry. I’m having really bad anxiety about it. My last post I said how I had unprotected sex and took a Plan B, and a few hours later has sex again but this time the condom broke.

I posted and asked if I should take another Plan B, but two Plan Bs in one day would honestly scare me because it could be very harmful.

I had someone comment that I’ll be fine, that basically the Plan B will work for both of those times. I also read online that one plan B can cover me till the time my next period comes.

According to both my apps I was on the second to last day of ovulating (which could be wrong, as in, I could’ve stopped ovulating a few days ago because my last period was a little weird and hard to track), I have irregular periods and I may have PCOS from the things I see, not a doctors diagnosis.

I know it’s best for me to get birth control, but there are some genetic things that stop be from being able to take birth control. I have to talk to a doctor and see if it’s possible. I understand that birth control is better.

I just need help understanding and knowing how to go about this. Will the one pill be fine and work for both the situations? Even if they were hours apart but in the same day?
