Two-Week Wait(TWW)
generalDefinition
The period between embryo transfer and the pregnancy test, typically 9-14 days, during which implantation either occurs or does not.
In IVF Treatment
The TWW is often described as the most emotionally challenging part of the IVF process. Symptom-watching is unreliable because progesterone supplementation mimics early pregnancy symptoms regardless of outcome.
Frequently Asked Questions
Can I take a home pregnancy test during the TWW?
You can, but it can be misleading. Testing too early can produce false negatives. If you received an hCG trigger shot, a home test may show positive for 7-10 days from residual trigger. Most clinics recommend waiting for the blood beta test.
What should I do during the two-week wait?
Continue your medications, keep routine gentle activities, and be kind to yourself. There is nothing you can do to cause or prevent implantation. Focusing on comfort rather than symptom-watching can help manage anxiety.
