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.
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.
