If you're formula feeding does anyone have any idea when you should start your first period after delivery?
just googled this:
Whether and how much you're nursing your baby is the biggest factor in determining how soon your body will resume its menstrual cycles.
The timing is different for every woman, and there's a huge range of what's considered normal, depending on your body and circumstances. As a result, the time frames mentioned below are approximate guidelines. If you're concerned, your healthcare provider can help evaluate your situation and make sure you're on track.
Nursing moms: One seldom-cited benefit of breastfeeding is that it delays your period. If you're breastfeeding exclusively, day and night, it can take a year or even longer before you have to run to the store for tampons, suffer from PMS, or cope with cramps. If you're lucky enough to have a baby who sleeps through the night from an early age, your period will likely return sooner typically in three to eight months. The same applies if you're supplementing with formula. In other words, the more often your baby nurses, the longer it will be before you get your period again.
Non-nursing moms: If you're formula-feeding your baby, you might start menstruating again as soon as a month after delivering your child, or it could take two or three months.
All moms: Bear in mind that your body will release its first postpartum egg before you menstruate. So if you don't start using birth control as soon as you start having sex again, you can get pregnant even before having your first period. If you're breastfeeding, don't be misled by the myth that you're not fertile many a nursing mother has been surprised by an unplanned pregnancy.
