The First Week After Embryo Transfer

What could be happening inside your body?

Day 0: The Embryo Is Placed

The embryo is gently placed inside the uterus. Standing, walking or using the washroom will not make it “fall out.”

Days 1–2: The Embryo Develops

After a Day-5 blastocyst transfer, the embryo may continue expanding and hatch from its protective outer layer.

Days 2–3: Initial Contact May Begin

The blastocyst may begin making contact with the receptive uterine lining. Implantation is a gradual process, not one instant event.

Days 3–5: Implantation May Progress

Early placental cells begin attaching to and moving into the uterine lining, creating the foundation for pregnancy.

Days 5–7: hCG Production May Begin

If implantation progresses, the developing pregnancy begins releasing hCG. However, levels may still be too low for a reliable test.

What Might You Feel?

You may notice mild cramping, light spotting, bloating or breast tenderness, or feel nothing at all. Symptoms cannot confirm implantation.

Continue Your Medicines

Take progesterone and all other medicines exactly as prescribed. Do not stop them because of spotting or an early home-test result.

Avoid Testing Too Early

An early test can give a misleading result. Always test on the date provided by your fertility clinic.

Every Embryo Follows Its Own Timeline

Symptoms - or no symptoms - cannot predict the outcome.
