Chances of pregnancy during period?

Sooooooooo. My boyfriend is in the military and during my last day and a half with him, my period had shown up 2 days before...buuuuut that didn’t stop us 🤷🏽‍♀️ lol

Anywho. We went at it quite a bit....and figured I’m on my period, so we didn’t use protection....

My period lasts about 5 days. Day 1 is light, day 2 is heavy asf, day 3 (which is most of when we were intimate) is usually light-medium, and days 4 and 5 are mostly light/spotting..

What’re the chances of me getting pregnant?

Should I have taken a Plan B pill to be safe?

I know chances are slim to none, buttttttt I’ve been lowkey nervous that maybe I should’ve just taken one.

Too little too late, now, if anything. Lol.

Yikes.

Input is greatly appreciated!
