After the whirlwind of pregnancy, labor, and those intense postpartum weeks, it's natural to wonder when your body will "go back to normal." For many people, this includes waiting for their period to return.

But what happens when it doesn’t?

The absence of a menstrual cycle after having a baby can be surprising and even concerning for some. Let’s unpack why this happens, what it means for your health, and when to consider seeking medical advice.

What’s happening in your body after pregnancy?

Pregnancy transforms your body in countless ways, and postpartum recovery is no less monumental. For many, periods don’t immediately return after childbirth due to hormonal changes. During pregnancy, the hormones estrogen and progesterone rise to support the growing baby.

After delivery, these hormones drop sharply, and your body begins producing prolactin, especially if you’re breastfeeding. Prolactin, the hormone responsible for milk production, also suppresses ovulation, which is why many breastfeeding parents experience a delay in the return of their periods.

This phenomenon is called lactational amenorrhea. It’s a natural process and can vary significantly from person to person. Some may see their period return within a few months postpartum, while others might go over a year without one, especially if they are exclusively breastfeeding.

How soon after giving birth can you get your period?

The timing of your period’s return after childbirth depends largely on whether you’re breastfeeding. If you are, the hormone prolactin, which supports milk production, can delay ovulation and menstruation for several months — sometimes until you reduce feedings or wean completely.

For those who aren’t breastfeeding, periods typically return 6 to 12 weeks postpartum, though this varies.

Your first period might be heavier, lighter, or different than before, as your body readjusts. This is usually normal, but if anything feels off — like heavy bleeding or severe pain — reach out to your doctor.

How do you know when your period is coming back after pregnancy?

The return of your period after pregnancy can feel unpredictable, but there are signs your body might be getting ready. Many notice changes as hormone levels start to rebalance.

For example, you may experience mild cramping, spotting, or the familiar sensation of premenstrual bloating. Other signs include changes in cervical mucus — it might become clearer or more slippery, similar to how it was before ovulation pre-pregnancy.

Breastfeeding can delay your period, so if you start nursing less frequently or weaning, this could signal the return of your cycle. That said, every body is different, and some may not notice any signs until the period suddenly arrives.

It’s also worth noting that ovulation often happens before your first postpartum period. This means you could technically become pregnant even before you start menstruating again. If pregnancy isn’t part of your plan right now, consider using contraception once you resume intimacy.

Breastfeeding and its role in delaying periods

If you’re breastfeeding, you can thank the hormone prolactin for keeping your period at bay. Prolactin helps with milk production, but it also suppresses ovulation. This natural suppression can mean no period for several months — or even a year — while you’re nursing.

However, this isn’t a hard-and-fast rule. Some people get their period back within a few months even if they’re exclusively breastfeeding, while others don’t see it until they’ve weaned their baby. It’s all about how your body responds to hormonal changes.

Fun fact: Breastfeeding isn’t birth control (well, not really)

While prolactin can suppress ovulation, it’s not a foolproof method of contraception. If you’re not ready for another baby just yet, talk with your doctor about birth control options that work for your postpartum lifestyle.

Why haven't I got my period after giving birth?

Breastfeeding isn’t the only reason your period might be MIA after pregnancy. Here are a few other possibilities:

  • Stress: Let’s be real, postpartum life is full-on. Chronic stress can impact the hypothalamus (the brain's control center for hormones) and disrupt your menstrual cycle.
  • Thyroid issues: Conditions like postpartum thyroiditis (an inflammation of the thyroid gland) can mess with your cycle. This condition affects about 5-10% of postpartum people, according to the American Thyroid Association, and both hypothyroidism and hyperthyroidism can disrupt the menstrual cycle.
  • Polycystic ovary syndrome (PCOS): If you had irregular periods before pregnancy, PCOS might still play a role postpartum. This condition can affect how often you ovulate, even after childbirth.
  • Hormonal imbalances: Beyond prolactin, other hormones like LH (luteinizing hormone) and FSH (follicle-stimulating hormone) might not be firing on all cylinders yet.
  • Low body weight or nutritional deficiencies: Significant weight loss or gain postpartum can influence your cycle. For some, rapid weight loss after giving birth, whether due to breastfeeding or lifestyle changes, might delay the return of menstruation.
  • Uterine or ovarian conditions: In rare cases, complications like Asherman’s syndrome (scar tissue in the uterus) or retained placental fragments can interfere with the return of your period.

When should you worry about no period after pregnancy?

In most cases, a delayed period postpartum is perfectly normal. But there are situations where it’s worth reaching out to a healthcare provider:

  • You’re not breastfeeding: If you’re not breastfeeding and your period hasn’t returned within 8-12 weeks postpartum, it’s worth discussing with your doctor.
  • Symptoms of hormonal issues: Feeling excessively tired, experiencing hair loss, weight changes, or mood swings could point to thyroid or other hormonal imbalances.
  • Severe pain or heavy bleeding: Postpartum bleeding (lochia) should taper off within a few weeks. If you experience a sudden return of heavy bleeding or severe cramping, it could indicate an issue.
  • You’re trying to conceive again: If your period hasn’t returned and you’re hoping to have another baby, you’ll need to ensure that ovulation has resumed.
  • You’re worried, even if everything else seems fine. (It’s always okay to ask for reassurance!)

Remember, you know your body best. If something feels off, trust your instincts.

How to support your body during this time

While your body is on its own schedule, there are ways to gently nudge things along — or at least support yourself while you wait:

  • Eat a balanced diet: Focus on nutrient-dense foods that fuel recovery and hormone balance. Think leafy greens, whole grains, and healthy fats.
  • Stay active: Gentle movement like walking or yoga can help regulate hormones and reduce stress.
  • Prioritise sleep: Yes, we know this one’s laughable when you have a baby, but every bit helps. Aim for rest when you can.
  • Check in with your mental health: Postpartum life can be overwhelming, and stress can impact your cycle. Don’t hesitate to reach out for support if you need it.

Not having a period after pregnancy is usually nothing to worry about, especially if you’re breastfeeding. Your body is doing a lot of behind-the-scenes work to recover and recalibrate. But if you’re ever unsure or feeling off, a quick chat with your healthcare provider can put your mind at ease.

Your postpartum journey is as unique as you are, and understanding what’s happening with your body is an empowering step in taking charge of your health.
