What to do if…
you have postpartum bleeding that seems heavier than expected and you feel lightheaded

Short answer

This can be an emergency. If your bleeding is heavy and you feel lightheaded or like you might faint, call 911 now (or have someone call) and get urgent medical care.

Do not do these things

  • Do not drive yourself to the hospital.
  • Do not stay alone or hold the baby if you feel faint.
  • Do not use tampons or a menstrual cup right now.
  • Do not take aspirin or NSAIDs (like ibuprofen/naproxen) unless your clinician told you to. If you’re prescribed aspirin or a blood thinner, don’t stop it suddenly—tell 911/EMS and the clinicians what you take.
  • Do not wait to “see if it stops” if bleeding is heavy or symptoms are worsening.

What to do now

  1. Lie down right away. If you’re dizzy, lie flat. If you feel like you may pass out, lie on your side. Keep your phone in your hand.
  2. Call 911 now (or have someone call). Say:
    • “I recently had a baby.”
    • “I’m bleeding heavily and I feel lightheaded / like I might faint.”
    • If relevant: “I’m soaking one or more pads in an hour,” “I’m passing large clots,” “my heart is racing.”
    • If you can estimate: ACOG describes very heavy postpartum bleeding as soaking two pads an hour for more than 1–2 hours—but with lightheadedness, call 911 even if you’re not sure about pad counts.
  3. Make the baby safe before anything else. If you’re alone, place the baby in a safe spot (crib/bassinet/on the floor on a blanket) so you’re not holding them if you faint. If another adult is present, have them take over baby care immediately.
  4. If you can safely do it, get ready for EMS. Unlock the door, turn on a light, and lie where you can be found quickly. Put pets away if possible.
  5. Go to the right place for postpartum emergencies. If you are told to self-transport (only if you are stable and not alone), go to the nearest Emergency Department or, if instructed by your hospital, Labor & Delivery triage. With dizziness/lightheadedness, EMS is safer than a car.
  6. Share key info (but don’t delay care). The date/time you delivered, any recent complications, your current meds (especially blood thinners/aspirin), allergies, and when the heavy bleeding started.

What can wait

  • You do not need to decide right now what caused the bleeding.
  • You do not need to measure exact blood loss.
  • You do not need to reach your OB office before getting help — the priority is urgent medical evaluation.

Important reassurance

Many people second-guess themselves after birth and worry about “overreacting.” Heavy bleeding plus lightheadedness is a valid reason to seek emergency help immediately.

Scope note

This is first-steps guidance only. Clinicians may check your vital signs, examine you, and treat the cause of bleeding, but your job right now is to get safely into urgent care.

Important note

This guide is general information and not a diagnosis or personalized medical advice. If you have heavy postpartum bleeding or feel dizzy/faint, seek emergency medical care right away.
