Pregnancy can have its challenges, but on the celebratory side, you are spared the menstrual cycle craziness of monthly mood swings, cramps, and bleeding. Of course, now that you have had your baby, you may be wondering when your period is likely to return. The short answer is…it depends.
The timing of your first period postpartum depends on whether or not you breastfeed. If you are formula feeding, Aunt Flo should arrive about six to eight weeks after the big day. However, if you are exclusively breastfeeding—meaning, your baby drinks absolutely nothing but breastmilk (other than vitamins or medicine)—your period will likely be delayed. That is because prolactin, the hormone released during breastfeeding, delays the restarting of your ovulating. No ovulation = no period.
Some women will not get a period for the entire time they are breastfeeding. Others will get their period while they are still breastfeeding, particularly after they have introduced bottles of formula, solid foods or when baby starts sleeping through the night.
Yes! Yes! Yes! Once your cycle comes back, you will ovulate two weeks before you get your first period, so you will have no advance warning that you are fertile! If you are not ready to get pregnant again, check out your birth control options. Hormonal birth control will not hurt your baby, but if they contain estrogen they may cause your milk supply to dip. Ask your practitioner about non-hormonal birth control methods including diaphragms, condoms, certain versions of the pill (progesterone-only pills do not reduce milk supply), and some IUDs, that are totally compatible with breastfeeding.
Brace yourself…the first period after giving birth is typically heavier than normal because there is extra blood in your uterine lining that needs to be shed. You may enjoy easier periods due to physical changes in the uterus and cervix, although some women experience stronger cramps.
Here is another surprise: After your first post-baby period, the next may show up early…or quite late. It can take a few months for your cycle to become regular again. Stash some period protection in your purse so you are not caught off guard. If you do get your period soon after giving birth, ask your doctor if it is safe to use tampons. Most women feel that pads are a better option until the vagina is completely recovered from delivery.
Though that first period after baby can be a doozy, the flow should not be so heavy that you are going through one pad per 1-2 hours. Call your doctor if you are experiencing any of the following:
Though you may wish your period would just stay away forever, remember that it is a sign of your body functioning normally after pregnancy. Practice self-care by getting plenty of rest, taking walks to relieve cramps, and snacking on healthy fats (hello, avocado toast!) and iron-rich lentils, prunes, meats, and foods cooked in a cast iron skillet.

If you have any medical questions and concerns about your child or yourself, please contact your health provider. Breastmilk is the best source of nutrition for babies. It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
