So my Bf and i were having sex and the condom broke so he cummed in me (we didn’t know till i had to fish it out of my vagina). Anyways it happened few days before my period (suppose to start today or tomorrow)

I took the plan b within the first 24hrs

But now i have small cramps that feel like a period cramp but not sure

I took a test and it came Back negative but it might be to early for that right?

What should i do?

This all happen outside my fertile window as well so my chances are very low right?
