What should you know about embryo transfer success?

Transfer places an embryo inside the uterus, but implantation happens later and cannot be felt or confirmed immediately. A positive blood test indicates that pregnancy hormone is present; your clinic may arrange follow-up testing and an ultrasound to check how the pregnancy is developing. A negative result does not identify one single cause. The embryo, the lining, hormonal support, timing, and underlying fertility factors may all be considered.

Use prescribed medicines exactly as directed, including any progesterone support, and attend the testing appointment your clinic gives you. Keep ordinary routines if you feel well, drink fluids, eat regularly, and choose gentle movement rather than strenuous exertion if advised. Do not stop treatment because of spotting or because you feel no symptoms; contact the clinic for specific instructions.

Contact your fertility team promptly for heavy bleeding, increasing pelvic pain, fever, faintness, shortness of breath, or marked abdominal swelling. Seek urgent medical help for severe pain, collapse, or breathing difficulty. Mild cramping or light spotting can occur after a procedure, but the clinic should help you judge what is expected for your treatment plan.

Ask which test will confirm pregnancy and on what day, whether your medicines should continue until that result, and which symptoms require an urgent call. You can also ask how embryo quality, lining preparation, and the transfer plan apply to your situation.
