Hi

I had unprotected sex with my boyfriend on the 8th day on my cycle. He didnt go in me at all, we used the withdrawal method. About 14 hours later i took Plan B. I didn't experience any side effects until about 5 days later. My period came but it was 2 weeks early and lasted for 4 days. It was a little lighter than how it is normally, but definitely still felt like a period. Should i consider this my period for the month and start counting 28 days again? I know Plan B screws up your cycle but I'm really confused, if someone could respond it would greatly help
Thanks!!
