i took the plan b in april right after my period, i had severe cramps for about a week, to where i couldnt get out of bed. my period never was messed up, nor did i have bleeding after it. the only thing that happened was severe cramps, and throwing up.
Its possible however plan b is only 85% effective. I actually got pregnant even though I took it 24 hours after intercourse.
I wanna know the same!! Let me know if you hear anything and I will do same!
