The two-week wait — that stretch of time between your embryo transfer and pregnancy test — is widely considered the hardest part of IVF. After months of preparation, injections, monitoring, and procedures, you're suddenly left in limbo. Waiting. Analyzing every twinge. Googling symptoms at 2 AM.
You're not alone in finding this difficult. This guide will help you understand what's happening in your body, what symptoms mean (and don't mean), and practical ways to stay sane until test day.
What's Happening in Your Body
After embryo transfer, your body enters a delicate phase where implantation may occur. Here's the timeline:
Embryo Hatches
The embryo breaks out of its protective shell (zona pellucida) and prepares to attach to the uterine lining.
Implantation Begins
The embryo attaches to and burrows into the uterine lining. This is when implantation spotting may occur.
Implantation Completes
The embryo is fully embedded. Cells that will become the placenta start forming and producing hCG.
hCG Rises
hCG levels increase enough to be detected by a blood test. This is typically when your clinic schedules your pregnancy test.
Symptoms: What They Mean (and Don't Mean)
Here's the frustrating truth: symptoms during the two-week wait are unreliable. The progesterone supplements you're taking mimic early pregnancy symptoms almost exactly. You cannot tell from symptoms alone whether you're pregnant.
| Symptom | Possible Causes |
|---|---|
| Cramping | Progesterone, implantation, transfer procedure, or nothing at all |
| Spotting | Implantation bleeding, progesterone irritation, or procedure-related |
| Sore Breasts | Progesterone (not necessarily pregnancy) |
| Fatigue | Progesterone, stress, or early pregnancy |
| Bloating | Progesterone slowing digestion, IVF medications |
| Nausea | Progesterone or early pregnancy |
| No Symptoms | Completely normal — many pregnant women have no symptoms |
The Bottom Line on Symptoms
Having symptoms doesn't mean you're pregnant. Having no symptoms doesn't mean you're not pregnant. The only reliable indicator is your blood test. Try not to drive yourself crazy analyzing every sensation.
Do's and Don'ts
âś“ DO: Continue Your Medications
Keep taking progesterone and any other prescribed medications exactly as directed. Don't stop until your clinic tells you to — even if you feel fine or think the cycle didn't work.
âś“ DO: Stay Hydrated
IVF medications can cause fluid retention and bloating. Drinking plenty of water helps your body function optimally and may ease discomfort.
âś“ DO: Take It Easy (But Not Bed Rest)
Light activity like walking is fine and may even improve blood flow. You don't need to lie flat for two weeks — research shows bed rest doesn't improve outcomes.
âś“ DO: Distract Yourself
Binge a TV series. Read books. Work if you can. Spend time with supportive friends. Keeping your mind occupied makes time pass faster.
âś— DON'T: Take Early Home Pregnancy Tests
Home tests can give false negatives (too early) or false positives (leftover trigger shot hCG). Wait for your official blood test to avoid unnecessary heartbreak or false hope.
âś— DON'T: Google Symptoms
Down that rabbit hole lies madness. You'll find stories of people with identical symptoms who got opposite results. It won't help — it will only increase anxiety.
âś— DON'T: Have Sex
Most clinics advise avoiding intercourse and orgasm during the TWW. Uterine contractions could theoretically interfere with implantation.
âś— DON'T: Do Strenuous Exercise
Skip the intense workouts, heavy lifting, and hot yoga. Gentle walking and stretching are fine. Your ovaries may still be enlarged from stimulation.
Managing Anxiety
The TWW is emotionally brutal. Here are strategies that actually help:
Breathing Techniques
The 4-7-8 technique can reduce anxiety in the moment: breathe in for 4 counts, hold for 7 counts, exhale for 8 counts. Repeat 3-4 times.
Limit Who You Tell
The more people who know, the more people will ask for updates. Consider limiting your circle during the TWW to reduce pressure and the number of conversations you'll need to have regardless of outcome.
Stay Present
Your mind will constantly jump to "what if." When you catch yourself spiraling, gently return to the present moment. What do you actually know right now? What can you actually control?
Plan for Both Outcomes
This might sound counterintuitive, but having a mental plan for either result can reduce anxiety. If it works, what's next? If it doesn't, what's the plan? Knowing you have a path forward either way can bring peace.
The TWW When You're Abroad
If you've had your transfer in Colombia, you have a unique TWW situation:
- Stay a few days: Most clinics recommend staying 2-3 days after transfer before flying home
- Flying is okay: There's no evidence that flying affects implantation after the initial rest period
- Take it easy on travel day: Have someone else handle luggage; don't strain yourself
- Blood test at home: Your Colombian clinic will tell you when to get your beta hCG test done locally, then you'll share results with them
Silver Lining: Being Abroad Can Help
Some patients find that being in a different environment — exploring MedellĂn, enjoying Colombian food, experiencing a new culture — actually makes the TWW easier. You're naturally distracted and have things to do besides analyze symptoms.
When to Call Your Clinic
Contact your medical team if you experience:
- Heavy bleeding (soaking a pad in an hour)
- Severe abdominal pain
- High fever
- Difficulty breathing or severe bloating
- Signs of ovarian hyperstimulation (rapid weight gain, severe bloating, decreased urination)
Mild cramping and light spotting are usually normal — but if you're worried, it's always okay to call.
Test Day
Your blood test (beta hCG) is typically scheduled 9-14 days after transfer, depending on your clinic. This measures the pregnancy hormone in your blood.
Results:
- Positive: You'll have another beta test in 48 hours to confirm hCG is rising appropriately (should roughly double). An ultrasound follows at 6-7 weeks.
- Negative: You'll stop progesterone and get your period. Take time to grieve — this is a loss. Then, when you're ready, discuss next steps with your doctor.
Whatever the outcome, you've done everything you could. The TWW is about waiting for biology to do its work — not about anything you did or didn't do.

What Research Says About the Two-Week Wait
Studies have consistently shown that strict bed rest after embryo transfer does not improve success rates and may actually be counterproductive by increasing stress and reducing blood flow. Normal daily activities are perfectly safe and even encouraged. The embryo is secure within the uterine cavity and cannot fall out from walking, working, or going about your normal routine. Focus on stress reduction, maintaining healthy habits, and keeping yourself gently occupied during this challenging time. Many clinics recommend light activity and staying mentally engaged as the best approach during the wait period. Trust that youve done everything in your power—now its up to biology.
