S.T.
No question is silly to ask no matter how many you have gotten pregnant. Yes, you can get pregnant soon after birth. They do say that you are more fertile after birth. Some people have children that are 9 months apart. I didn't realize that and my two older boys are 1 year and 3 weeks apart. The pull out method always make me wonder...how successful can you be.
Anyways, you can wait and then test yourself to see if you are and if you still question you can call your OB. My period has never been regular or normal before and after births. I noticed after each birth, the number of days having my period were shorter which was great, but everyone is different. Just let me tell you this, A.....If you are pregnant, CONGRATUALTION!!!!!!!!! If you're not, well it wasn't meant to be. You got me curious now....let me know if you are or aren't please. Thanks.
