Apologies if this is in the wrong spot..
I havent had a period since sept. 2012 as ive been pregnant twice, and breastfeeding. 3 days ago I got my period again (the day i switched my baby to milk). This morning when i got up i had some cramps but when I sit down I have a very sharp stabbing pain in my vagina that goes right up to my mid section. Just wondering if anybody might know whats causing it? Should I be worried? Also im 23 and have had my tubes tied if that helps? Thank you in advance.
