Lochia is the vaginal discharge after birth, made up of blood, uterine tissue, mucus, and bacteria as your uterus heals from the placental site. Every postpartum mother experiences it — whether after vaginal or C-section delivery — and it lasts an average of 4-6 weeks. Knowing what’s normal week by week (and what’s not) helps you recover with confidence and recognize the warning signs of postpartum hemorrhage and infection.
📌 Key Takeaway: According to the American College of Obstetricians and Gynecologists (ACOG), a full-term pregnancy lasts 39-40 weeks, with key fetal milestones occurring almost every week. This guide gives you evidence-based, practical guidance you can apply today. For a related deep dive, see our guide on postpartum recovery timeline.
What Is Lochia?
After delivery, the uterus must heal a wound the size of a dinner plate where the placenta detached. As blood vessels seal off and the uterine lining sheds, you discharge:
- Blood (initially heavy)
- Decidua (uterine lining)
- Cervical mucus
- Bacteria
- Fragments of fetal membrane and tissue
Lochia happens regardless of vaginal birth or C-section, although flow is sometimes slightly less in the first 24 hours after C-section.
Week-by-Week Lochia Guide
Days 1-3: Lochia Rubra (Red)
| Feature | Description |
|---|---|
| Color | Bright to dark red |
| Flow | Heaviest — like a heavy period or heavier |
| Volume | Should not soak more than 1 maxi pad per hour |
| Clots | Small clots (smaller than a quarter) are normal; large clots (larger than a golf ball) need evaluation |
| Smell | Bloody, similar to menstruation; should not smell foul |
| What to use | Hospital-grade or maternity pads (not tampons) |
Activity tip: Standing up after lying down often releases pooled blood — a “gush” upon standing is normal.
Days 4-10: Lochia Serosa (Pink-Brown)
| Feature | Description |
|---|---|
| Color | Pink, brown, or watery red |
| Flow | Moderate, decreasing |
| Volume | Light to moderate, like a regular period |
| Clots | Few or none |
| Smell | Earthy, mild; not foul |
| Activity link | Doing too much can return flow to bright red — listen to your body |
Days 11-28+: Lochia Alba (White-Yellow)
| Feature | Description |
|---|---|
| Color | Whitish, yellowish, or pale brown |
| Flow | Light, like discharge |
| Volume | Pantyliner is usually enough |
| Clots | None |
| Smell | Mild |
| Duration | Continues for 2-4 more weeks |
By 4-6 weeks postpartum, most women have minimal or no lochia. Some have light spotting up to 8 weeks.
What’s Normal
- Heavy flow that gradually tapers
- Brief return to red after activity (signal to rest more)
- Period-like cramps (afterpains), especially during breastfeeding
- Small clots in the first few days
- Lochia continuing 4-6 weeks total
What’s NOT Normal — Call Your Provider Immediately
Postpartum Hemorrhage (PPH) Warning Signs
PPH affects 1-5% of deliveries and is a leading cause of maternal death. Get help immediately for:
- Soaking more than 1 maxi pad per hour for 2 hours straight
- Large clots (larger than a golf ball) repeatedly
- Sudden return to bright red bleeding after it had become brown/pink (especially after week 1)
- Lightheadedness, dizziness, racing heart
- Pale skin, cold/clammy
- Bleeding gushing from the vagina
Endometritis (Uterine Infection) Signs
- Foul-smelling lochia (rotten odor)
- Fever 100.4°F (38°C) or higher
- Chills
- Severe lower abdominal pain or tenderness
- Persistent or worsening uterine pain
Other Concerning Signs
- Bleeding lasting more than 6 weeks without tapering
- Bleeding stopping then restarting heavily
- Severe one-sided pelvic pain
- Tissue passage larger than a golf ball
Lochia After C-Section
Despite popular belief, you DO bleed after a C-section. The placental site heals the same way:
- Initial flow may be slightly lighter than vaginal birth in first 24-48 hours (some blood is suctioned during surgery)
- After day 2-3, flow is similar to vaginal birth
- Total duration similar (4-6 weeks)
- Watch for additional incision-related infection signs (redness, drainage, opening)
For surgical recovery details, see our C-section recovery guide.
Lochia and Breastfeeding
Breastfeeding releases oxytocin, which makes the uterus contract:
- You may feel strong cramping (“afterpains”) during nursing, especially with second+ babies
- Lochia may flow more heavily during/right after nursing
- This is good — it speeds uterine return to pre-pregnancy size
Managing Lochia Comfortably
Supplies You’ll Need
- Hospital-grade maxi pads (10-15 thick first week)
- Adult disposable underwear or postpartum mesh underwear
- Postpartum recovery underwear (reusable, like Frida Mom)
- Pantyliners for weeks 3-6
Avoid
- Tampons — increase infection risk; not safe until 6-week clearance
- Menstrual cups — same reason
- Douching — never recommended
Help Healing
- Rest — the more you push activity, the more flow can resume
- Hydrate — supports tissue healing
- Eat iron-rich foods to replace blood loss (see iron foods for pregnancy/postpartum)
- Pelvic rest until cleared at 6-week visit
- Monitor pad changes to track volume
When Will I Get My Period Back?
After lochia ends, the next period varies:
| Feeding Method | Typical Return of Period |
|---|---|
| Exclusive breastfeeding | 6 weeks - 18 months (often suppressed) |
| Mixed feeding | 6 weeks - 6 months |
| Formula feeding | 4-12 weeks |
The first period after birth is often heavier and more painful than usual. Subsequent periods normalize.
Important: You can ovulate before your first period — use contraception if you want to avoid pregnancy.
Differences Between Lochia and Postpartum Hemorrhage Bleeding
| Lochia (Normal) | PPH (Emergency) |
|---|---|
| Tapers over weeks | Sudden heavy increase |
| Clots smaller than golf ball | Large clots |
| Steady or decreasing | Soaking pads quickly |
| No dizziness | Lightheaded, racing heart |
| Mild cramps | Severe pain |
Frequently Asked Questions
How long does lochia last?
Total lochia lasts 4-6 weeks on average. Heavy red lasts 3-5 days; pink/brown for 1-2 weeks; light yellowish for several more weeks.
Is it normal to pass clots after birth?
Small clots (smaller than a quarter) in the first few days are normal. Clots larger than a golf ball, or repeated large clots, warrant a call to your provider.
Why does my bleeding go away then come back red?
This usually means you’ve been too active. Lay down, rest more, hydrate, and re-evaluate. If bleeding stays heavy or smells foul, call your provider.
Can I use tampons during postpartum bleeding?
No. Tampons increase infection risk while the cervix is still partially open and tissue is healing. Use only pads or postpartum underwear until your 6-week visit.
When should I worry about postpartum bleeding?
Call right away for: soaking 1 pad/hour for 2+ hours, large clots, foul-smelling lochia, fever 100.4°F+, severe pain, dizziness, or lightheadedness.
