Implantation after embryo transfer: what to know

After an embryo transfer, the embryo may attach to the lining of the uterus. This is a biological process that cannot be seen or felt directly. Mild cramps, pelvic sensations, breast tenderness, fatigue, or light spotting may occur, but medicines and the approaching period can cause similar changes.

A negative or positive sensation is not a reliable way to judge the outcome. The clinic may prescribe micronised progesterone to support the uterine lining. Use it exactly as directed and do not stop it because of spotting or because you feel well unless the fertility team tells you to.

Take prescribed medicines on schedule, keep the pregnancy-test appointment, and follow the clinic's advice about activity. Ordinary gentle movement is generally compatible with recovery, but follow any personalised restrictions. Avoid changing medicines or adding supplements without checking with the team.

Record bleeding, pain, and medication doses if that helps you describe symptoms. A home test taken too early may be difficult to interpret, especially if fertility medicines have affected hormone levels. The clinic's test date gives the clearest next step.

Contact the fertility clinic promptly for bleeding that is becoming heavier, significant or one-sided pelvic pain, fever, dizziness, or shortness of breath. Seek urgent care for severe pain, fainting, heavy bleeding, or trouble breathing. These symptoms need assessment regardless of whether implantation has occurred.

Ask when to test, whether to continue each medicine if spotting occurs, which symptoms need same-day advice, and when the clinic will review the result and plan the next step.
