Mother and Baby

Is it normal to have irregular periods after pregnancy/when breastfeeding?

Periods. Nobody likes them but nobody wants them to be non-existent or irregular without explanation. 

We might associate a regular period with being healthy so when it is unpredictable, especially after birth, we might start to worry.

Fear not! We've found out everything you need to know about irregular periods after birth and pregnancy to put your mind at ease.

Is it normal to have irregular periods after having a baby?

Pregnancy and childbirth have a drastic impact on the hormones in our body as they prepare us for childbearing, birthing and breastfeeding. Hormone levels do not go back to normal immediately after birth meaning the hormones which usually regulate our periods are less important during this busy time for your body. It is completely normal for women to experience irregular periods after birth and changes in the frequency and volume of your period after pregnancy are possible.

Do periods change after having a baby?

As well as changes in your hormones there are other factors that can influence your periods post-birth. Women gain a significant amount of weight during pregnancy and after birth, this doesn't always just disappear. Some mums might even lose weight too quickly due to lack of sleep and a poor diet. Weight has a strong influence on the hormones in the body and this further affects your menstrual cycle. Ovulation also plays a key role in our menstrual cycle and as the frequency of ovulation decreases after pregnancy this may lead to irregular periods.

Are periods irregular while breastfeeding?

Periods can almost definitely be irregular or non-existent while breastfeeding. Breastfeeding mothers begin ovulation after birth much later. Prolactin, the hormone responsible for the secretion of milk suppresses the process of ovulation which means while a mother is breastfeeding, prolactin will remain in the body, affecting the ovulation process. Only once a successful ovulation cycle is completed will you start menstruating again.

How long after giving birth will my period come back?

Hormones may reach normal levels more quickly depending on whether you exercise or have sex after birth but they often remain erratic and unpredictable for months. If you exercise you are more likely to regain your pre-pregnancy body and maintain your weight. This helps restore the hormone balance in your body which is a significant factor in determining your periods. Try these exercises that you can do with your baby.

Having a healthy diet post-birth is very important as it helps to restore the nutrients lost during pregnancy and childbirth. It is a good idea to eat a balanced diet of fruit, vegetables, nuts and grains to give your body the important micronutrients needed to repair the body. A healthy diet will also influence any hormone imbalances in the body.

Trying to be calm and stress-free with a newborn is easier said than done. The lack of sleep, new responsibilities and the emotional impact of having a baby can make new mums very stressed. However, you guessed it, being stressed also has an impact on your hormone levels. Try meditation/mindfulness techniques, talking to friends and family or post-natal yoga (when you get a chance!) to keep stress levels low.

If you want your periods to come back regularly, avoid contraceptives. These further interfere with ovulation and can affect your menstrual cycle. There are contraceptive methods that do not involve hormones such as condoms or the intrauterine device (IUD) which you can discuss with your doctor.
