Besides irregular menstruation there are other changes in woman’s body after giving birth, including the following.

1. The number of days between periods increases. This can last for up to a year after giving birth.

2. Women may have headaches, constipation, backaches and urinary incontinence, which usually improve gradually. However, some people experience these conditions long term and they can be quite bothersome.

3. There will be changes in your hormones during the first few weeks of delivery and when you are breastfeeding. This will impact how you feel both physically and mentally. This can take some getting used to.

4. In the months following childbirth, many women will also notice increased energy, less anxiety and more movement.

5. Women who have given birth will experience a decrease in the number of dark patches on the skin. It happens most likely because there is less blood supply to those areas. This is a short-term change and will fade away in around six months to a year after childbirth.


6. Women who have given birth may notice a decrease in their libido, or sexual desire. However, sexual satisfaction is something that every woman experiences differently and it will only return once you have had another child.

7. A woman’s body shape may also change after giving birth. Loose skin under the arms and belly can occur due to the removal of the womb and ovaries during childbirth. This leaves an empty space for your skin to return to normal shape. You can return back to your normal state in a month to a year depending on the intensity of exercise you do.

8. Some women experience changes in their skin, hair and nails as a result of pregnancy and childbirth.

Hair loss is a common situation after giving birth and it may continue longer in breastfeeding women.

When to expect first period?


Right after giving birth for six to eight weeks you’ll have vaginal discharge of blood, mucus and uterine tissue. However, you shouldn’t mistake it for menstrual bleeding. It is not your period bleeding, it is lochia. It is bright red in color, but flow is heavier than period blood. There are special maternity pads for that case and they are thicker than usual ones.
Women who have had cesarean section delivery. will also have lochia, but amount and duration will be less. Because during surgery doctors manually remove placenta and clean the uterus.

When lochia finally ends for some time you won’t have your period. Your actual period may start after several weeks or even months. It is really difficult to predict when it will start, as everyone is different and our bodies differently react to changes. Basically, whether you are breastfeeding or not plays a key role on when your period will return.

When not breastfeeding…

When bottle feeding a baby your period will probably return in five to eight weeks after childbirth. If you combine breastfeeding with bottle feeding, you’ll get your period approximately at that time or a bit later.

When breastfeeding…

If you fully breastfeed your baby, you’ll get your menstruation much later. It may take from three to eight months to return or until you stop night-time breastfeeding. Prolactin hormone promotes breast milk production and it also has impact on reproduction system. High level of prolactin wards off ovulation, which causes delay in menstruation also.

Reasons for not having menstruation after giving birth


1. Some people experience a shorter or longer delay in return to regular cycles. It can be attributed to certain factors such as breastfeeding, hormonal change or stress levels.

2. For some people, it is normal to not have your period in the days before and after you ovulate, but there can be another cause for lack of periods. Namely menstrual irregularities caused by hormonal imbalance or polycystic ovarian syndrome (PCOS).

3. If you or your partner has a condition that causes semen to have a foul smell, such as trichomoniasis, you may be less likely to menstruate.

4. Stress and anxiety will also cause lack of periods, since stress hormones inhibit the release of other hormones that regulate the menstrual cycle.

5. Certain medications you may be taking for pain or acne may also cause lack of periods in some people, especially anabolic steroids and birth control pills.

6. Lack of periods can also occur because of bleeding from the vagina or other abnormalities, such as a pregnancy outside the uterus.
