depends on if you are breast feeding or not..If you are, you may not get your period until after you stop breast feeding...
I'm breast feeding and haven't had a period since I gave birth in September, almost 7 months ago.
I say this often but everyone is different. I stopped breast feeding and three weeks later I had a period. I know of friends who have gone two or three months after breast feeding that still haven't had a peirod. It really denpends on your body. Were you a regular girl before having kids? Did you use the pill? Did you use fertility drugs to get pregnant? All those kind of things can effect the menstral cycle. Unless you are wanting another baby enjoy the time away from Aunt Flow. She will come back soon enough
Have you had unprotected sex? Maybe you need a hpt? Otherwise, as the previous comment said, everyone is different. I for one had a regular period all the time even with breastfeeding, yuck.
