Bottom line up front: The two-week wait — the period between embryo transfer and your pregnancy blood test — is widely described as the most emotionally challenging part of IVF. When you are doing it in a foreign country, the experience takes on an additional dimension. Here is how to navigate it, whether you stay in Colombia for your beta or fly home to wait.
What Is Actually Happening During the Two-Week Wait
After your embryo transfer, the embryo needs to hatch from its outer shell, attach to the uterine lining, and begin implanting — a process that takes roughly six to ten days. During this time, there is genuinely nothing you can do to influence the outcome. The embryo's chromosomal makeup and the receptivity of your uterine lining have already been determined. Your job now is to continue your prescribed progesterone support and take care of yourself.
This is easy to say and enormously difficult to live. The uncertainty is the hardest part. You are simultaneously pregnant and not pregnant, hopeful and terrified, wanting to test early and knowing you should not. Every physical sensation — cramping, spotting, fatigue, breast tenderness — gets analyzed for meaning, even though these symptoms are also side effects of the progesterone you are taking.
What the Research Says About Stress and Implantation
Despite widespread worry, research has not demonstrated that stress during the two-week wait negatively affects implantation rates. A large meta-analysis found no significant association between emotional distress and IVF outcomes. This does not mean your feelings do not matter — of course they do. But it does mean you can stop worrying that worrying is hurting your chances. It is not.
Staying in Colombia vs Flying Home
Most Colombian clinics recommend staying for 24–48 hours after a fresh transfer before flying. For frozen embryo transfers, some clinics are comfortable with patients flying the same day or the next day. There is no strong evidence that flying affects implantation, though many clinics advise caution out of an abundance of care.
If you stay in Colombia for the full two weeks, you get the advantage of easy access to your clinic if any questions arise, the relaxed environment of MedellĂn or Bogotá, and the absence of your regular stressors (work, commute, household demands). Many patients describe their two-week wait in Colombia as surprisingly peaceful — walking through El Poblado, eating fresh fruit, sitting in the warm air, exploring at a gentle pace.
If you fly home, you return to your support network, your own bed, your routine. You can have your beta (blood pregnancy test) done at a local lab and send the results to your Colombian clinic. Both approaches are medically acceptable.
Practical Tips for the Wait
Stay on your medications exactly as prescribed — progesterone suppositories or injections are not optional. Stay hydrated and eat well, which is easy in Colombia with abundant fresh produce and clean water. Walk gently — moderate activity is fine and better than bed rest, which has not been shown to improve outcomes. Avoid hot tubs, saunas, and heavy exercise. Do not take a home pregnancy test before day 10–12 post-transfer, as earlier results are unreliable and a premature negative can cause unnecessary distress.
đź’ˇ MedellĂn During the Two-Week Wait
If you are staying in MedellĂn during your wait, the El Poblado and Laureles neighborhoods offer gentle walks, excellent coffee shops for reading or journaling, botanical gardens for peaceful mornings, and more restaurants than you could visit in a month. The consistent warm weather means you are never stuck indoors. Many patients say the wait in MedellĂn was more manageable than it would have been at home.
