Implantation Bleeding: Pink/Brown Discharge & Cramps – What It Means

Light pink or brown spotting 10–14 days after ovulation can be implantation bleeding—when the blastocyst attaches to the endometrium. It's typically:

• Scant (spotting only, not filling a pad)
• Pink, brown, or light red
• Brief (hours to 1–2 days)
• Accompanied by mild cramping

But It's Not Definitive

Similar bleeding can occur from:

• Hormonal fluctuations (estrogen withdrawal)
• Cervical irritation (exam, intercourse)
• Early pregnancy loss (chemical pregnancy)
• Ectopic pregnancy (urgent)
• Breakthrough bleeding on hormonal contraception

What to Do

1. Track timing relative to ovulation/expected period.
2. Take a home pregnancy test at/after missed period (first morning urine).
3. If positive or uncertain, see a provider for quantitative hCG and ultrasound.
4. Seek immediate care for heavy bleeding, severe pain, dizziness, or shoulder pain.

Only hCG confirmation + intrauterine gestational sac on ultrasound confirms viable intrauterine pregnancy.
