I was due right around the 24th, 25th of december for my period, I felt the usual pre menstral cramping, so that day I started exercising to subside it coming bc my BF was going to be home from work the 24th. We had intercourse from the 24th-28th, unprotected and no prevention, I got my period the 29th only for 3 days, we had intecourse the 31 the day it ended. So I'm thinking my period should be coming the 29th of Jan, and the week before my expected period I am tired and I get those cramps like your going to get your period but its low and either to the right or left and sometimes I feel like somethings moving like butterflies (I know thats impossible but so weird) I am already a mom of one so I wasn't sure if the signs and symptoms could come earlier the second time aound, and I don't have an appetite. Could I be pregnant?
