What Is Implantation Bleeding?

Implantation bleeding occurs when the fertilised egg attaches to the lining of the uterus, typically 10-14 days after conception. It's one of the earliest signs of pregnancy, affecting approximately 25% of women.

What Does It Look Like?

Implantation bleeding is typically: - **Light pink or brown** in colour (not bright red) - **Very light** - just a few spots, not enough to fill a pad - **Not accompanied by clots** - **Painless** or with very mild cramping

Implantation Bleeding vs Period

| Feature | Implantation Bleeding | Period | |---------|----------------------|--------| | **Colour** | Pink or brown | Bright red (starts) | | **Flow** | Very light spotting | Moderate to heavy | | **Duration** | 1-3 days | 3-7 days | | **Clots** | No | Yes, often | | **Cramping** | Mild or none | Moderate to severe | | **Timing** | 10-14 days after conception | 28 days after last period |

How Long Does It Last?

Implantation bleeding typically lasts **1-3 days**. It's usually just light spotting. If bleeding is heavier or lasts longer, it may not be implantation bleeding.

When to Worry {#when-to-worry)

Contact your GP or midwife if:

  • Bleeding is heavy (soaking a pad)
  • Bleeding is bright red
  • You have severe cramping
  • Bleeding lasts more than a few days
  • You feel dizzy or faint

Frequently Asked Questions

### How do I know if it's implantation bleeding or my period?

Implantation bleeding is much lighter than a period, usually pink or brown (not red), lasts only 1-3 days, and doesn't have clots. If you're unsure, take a pregnancy test.

Can implantation bleeding be heavy?

No. Implantation bleeding should be very light spotting. If you're experiencing heavy bleeding, it's more likely your period or a different type of bleeding that should be checked by a doctor.

Can I have implantation bleeding and still be pregnant?

Yes! Implantation bleeding is actually a sign of pregnancy. It occurs when the embryo attaches to your uterus. If you have light spotting around 10-14 days after conception, take a pregnancy test.
