In my opinion and with my experience after having 2 kids it really varies. I breastfed for almost 1 yr with my first and about 6 mos with my 2nd. I believe I got my period either in the 7th or 8th month after being pregnant after both kids. I have heard stories where some women never even got their period bt kids. That is why the OBs are pretty quick to encourage some form of a birth control after you give birth reminding you that even when you're nursing you can still get pregnant. I always think it's best to let your body get back into "normal" mode for a bit before getting pregnant again b/c it seems like it just makes for a healthier pregnancy but that is solely my opinion not really based on any medical research. Maybe this doesn't pertain to you, but I do know after having c-sections, it is best to allow your body some recup time. I had a friend that lost a baby after having a ruptured uterus and they thought it had some relation to her having her babies too close together (not enough healing time in between). Not to scare you at all . . . but I just wanted to share my thoughts on why I think it's a good idea to sometimes wait a bit between pregnancies since it can do a number on your body. I have no idea how old your baby is and quite honestly it's not place to tell you what to do. I have quite a gap between my kiddos but that was done on purpose and I haven't had any issues yet with fertility. I would definitely check with your OB/GYN for the best advice because really it comes down to your health, fertility, and age, I think. They will give you more research based facts rather than opinions. Best of luck to you!
