What are the chances of pregnancy when having s*x while on my period?

Question

My period usually last 7 days, It was around my 4th day when we did it. It kept bleeding afterwards, but in a couple of hours my period stopped completely. Today is the 5th day and it seems like the period is gone. Does this relate to having sperm in me during my period.

But anyways, to make sure, im taking plan b. I took it within 24 hours so i should be okay. i hope..

and no, plan b isn't the one that stopped my period because it stopped before i took it. Any ideas anyone???

Answer 1

I've read that having s*x during your period can actually shorten it. neat huh? I guess all the moment coaxes the rest of the blood out.  

Answer 2

1% read the box the pill came in

Answer 3

It's a slim chance of being able to get PG, but then it is still possible if you have irregular periods.
