Implantation Timeline After Transfer

Your implantation timeline

Key milestones

  • 1. Implantation begins — the embryo starts attaching to the uterine lining.
  • 2. Implantation completes; hCG production ramps up.
  • 3. hCG becomes detectable in blood; clinic beta test is due.
This timeline is an estimate based on typical embryo development and is not medical advice. Follow your clinic's exact schedule.

What implantation feels like

Implantation usually happens 1-5 days after a blastocyst (Day 5) transfer, or 2-5 days after a Day 3 transfer. Many people feel nothing at all.

Light spotting, mild cramps, or breast tenderness can occur but are not required signs. A home pregnancy test is unreliable before the clinic's beta.

When can I test?

Wait for your clinic's beta hCG blood test (typically 9-14 days after transfer). Testing early with urine strips often gives false negatives and unnecessary stress.
