Your first period after having a baby can be intense, often heavier with more cramping, clots, and irregular flow than you're used to, as your uterus sheds the extra lining, but it usually settles down; expect it a few weeks to months after birth, earlier if formula-feeding, later if breastfeeding, and see a doctor for soaking through pads quickly, large clots, severe pain, or bad odor.
Menstruation after birth usually occurs early in women who do not breastfeed and do not breastfeed regularly. Menstruation in the first cycles after birth may be heavier and more irregular, and pain may increase due to uterine contractions and stimulation from breastfeeding.
Your first postpartum period may be met with a heavy cycle, pelvic pressure, achiness and a return to tampons – which might be suddenly slightly more uncomfortable (ouch!).
When your first postpartum period does come, there's a good chance your flow could be a little different to what you're used to – it could be heavier, lighter, longer or shorter than your pre-baby periods. The blood might even be a different colour or texture.
Most women can expect their first couple of periods after giving birth to be heavier than those they experienced before pregnancy. Menstrual blood should look like you expect: a bright red that fades into a darker, brownish red.
After the initial six-week postpartum period, you can expect healthy, gradual weight loss. You can start exercising regularly while maintaining a balanced diet during this period. A sustainable and healthy rate of weight loss during this time is about one to two pounds (0.5-1 kg) per week.
Your first postpartum period after can be irregular, heavier, more painful, or delayed—especially if you're breastfeeding. For some, menstruation after giving birth is just a temporary inconvenience, but for others, it's a sign of deeper hormonal imbalances.
In some cases, runny period blood may be a symptom of an underlying menstrual disorder or gynecological condition. Conditions such as menorrhagia (heavy menstrual bleeding), polycystic ovary syndrome (PCOS), or uterine fibroids can cause changes in menstrual blood consistency and flow.
Call your doctor now or seek immediate medical care if: You have signs of hemorrhage (too much bleeding), such as: Heavy vaginal bleeding. This means that you are soaking through one or more pads in an hour.
Your period gets worse
After birth, your uterus is bigger than before, which can cause more endometrium (the lining inside your uterus) to shed during your period. Structural defects, thickening of the uterus, and even thyroid disorders can trigger worse periods postpartum.
Lochia will smell like menstrual blood. Some describe it as musty, metallic, sour or stale. But it shouldn't smell fishy or foul. This could mean bacteria has caused an infection.
Quick Summary
Most people wear pads for up to 6–8 weeks after giving birth, though the timeline can vary. In the first few days, the bleeding (lochia) is heavy and may include clots. For this, you'll want a high-absorbency pad.
There is consensus that the postpartum period begins upon the birth of the newborn. The end is less well defined, but is often considered the six to eight weeks after birth because the effects of pregnancy on many systems have largely returned to the prepregnancy state by this time.
For the first couple of days after giving birth, you'll be able to feel the top of your uterus near your belly button. In a week, your uterus will be half the size it was just after you gave birth. After two weeks, it will be back inside your pelvis. By about four weeks, it should be close to its pre-pregnancy size.
Blood can sit in the vagina when you are lying or sitting down. If that happens and you get up, you can feel a gush, which is normal. Some women also experience a gush when coughing, sneezing or laughing.
It is impossible to stop a period once it starts, nor for specific days. However, some birth control therapies can help reduce or stop periods altogether.
This tissue, which consists of the decidual lining that develops during the menstrual cycle or early pregnancy, can pass intact or in pieces, frequently accompanied by cramping and discomfort. While understandably concerning, a decidual cast is generally not a serious or life-threatening condition.
Menstruation can sometimes decrease milk production
After ovulation, estrogen and progesterone levels in the body rise and calcium levels fall. The increase in these hormones can cause a decrease in milk production for some women.
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.
“Period cramps typically feel stronger than pregnancy cramps. If you think you're pregnant or missed your period, it's a good idea to take a pregnancy test to confirm.”
In the first week postpartum, many shed another 5 to 8 pounds (2 to 3.5 kg) as their body naturally eliminates retained fluids, like excess blood and water weight. Some people lose up to 20 pounds (9 kg) within the first few weeks after delivery. However, postpartum fat loss takes more time.
The 3-3-3 rule for weight loss is a simple, habit-based method focusing on three key areas: 3 balanced meals a day, 3 bottles (or ~1.5L) of water by 3 PM, and 3 hours of physical activity per week, aiming for consistency over complex diets. It simplifies fat loss by establishing rhythm through consistent eating, adequate hydration to support metabolism, and regular movement, promoting sustainable health without intense calorie counting or restrictive rules, says Five Diamond Fitness and Wellness, Joon Medical Wellness & Aesthetics, and EatingWell.
The 5-5-5 rule is a postpartum guideline for the first 15 days of recovery, emphasizing rest to help the new parent heal and bond with the baby, by spending 5 days in bed, followed by 5 days on the bed, and then 5 days near the bed, gradually increasing activity while prioritizing rest, nourishment, and self-care over chores or visitors. It's a framework for creating boundaries and slowing down to prevent overexertion, though individual recovery needs should guide the pace.
The 40-day rule after birth, often called confinement or "The Golden Month," is a widespread cultural tradition emphasizing a mother's deep rest, healing, and bonding with her newborn, with family often handling chores and visitors, promoting physical recovery (like stopping bleeding) and mental well-being, rooted in ancient practices from Asia, Latin America, and religious traditions like Judaism and Christianity. Key aspects involve nourishing the mother, sheltering her from stress, and focusing solely on resting and bonding, a stark contrast to Western pressures to "bounce back" quickly.
