After an intrauterine insemination (IUI), the most important step is to rest on the table for at least 10 minutes before getting up. From there, the next two weeks are about giving your body the best chance at implantation while staying sane during the wait. Here’s what actually matters during that window.
Rest Right After the Procedure
Your clinic will likely ask you to lie still for 10 to 15 minutes after the catheter is removed. This isn’t just a courtesy. A study comparing different rest periods found that women who stayed lying down for 10 minutes had a clinical pregnancy rate of about 16%, compared to just 4.5% for women who rested only 5 minutes. Extending rest to 20 minutes didn’t produce a statistically significant improvement over 10 minutes, so there’s no need to stay flat for half an hour. Ten minutes is the sweet spot.
Once you leave the clinic, you can drive yourself home and go about your day normally. Bed rest beyond that initial window hasn’t been shown to improve outcomes.
Activity During the Two-Week Wait
Light to moderate exercise is fine. Walking, gentle yoga, and everyday movement won’t interfere with implantation. What you want to avoid are high-intensity workouts, anything that involves twisting your torso or going upside down, and heavy lifting. Strenuous chores like moving furniture fall into this category too.
Most clinics also recommend avoiding sexual intercourse for at least 24 to 48 hours after the procedure, and some suggest holding off longer if you used fertility medications that stimulated multiple follicles. The concern is that your ovaries may be temporarily enlarged and more sensitive to physical impact.
Medications and What to Avoid
If your cycle involved injectable hormones to stimulate ovulation, your doctor may prescribe progesterone support during the two-week wait. This typically comes as a vaginal suppository or gel that you use daily, and research shows it can significantly increase live birth rates for women who were on injectable fertility drugs. Women who used only oral ovulation-stimulating medication don’t appear to get the same benefit from added progesterone, so your protocol depends on how your cycle was managed.
For pain relief, stick with acetaminophen (Tylenol) rather than ibuprofen or other anti-inflammatory painkillers. Anti-inflammatory drugs affect the enzymes involved in building the uterine lining, and while the research on their impact during this specific window is mixed, most fertility specialists recommend avoiding them as a precaution. If you’re already taking any anti-inflammatory medication for another condition, check with your clinic before stopping it.
What to Eat
No single food will make or break implantation, but certain nutrients support the process. Folate is the most well-studied: higher folate levels are associated with higher implantation rates in assisted reproduction. You’ll find it in beans, lentils, and leafy greens, and most prenatal vitamins contain it. Omega-3 fatty acids from sources like walnuts and fish support reproductive health for both partners. Couples who ate eight or more servings of seafood per cycle conceived in less than half the time of those who ate less, according to one study tracking dietary patterns and fertility.
Plant-based protein sources, full-fat dairy, and foods rich in antioxidants (like tomatoes and citrus fruits) round out a fertility-friendly diet. None of this requires a dramatic overhaul. If you’re already eating a balanced diet and taking a prenatal vitamin, you’re doing what matters.
Normal Symptoms vs. Warning Signs
Mild cramping after IUI is completely normal. The catheter passes through your cervix, which can cause light discomfort that lingers for a day or two. Some light spotting is also common and not a cause for concern.
Call your clinic if you experience any of the following:
- Worsening abdominal pain that doesn’t improve over time or responds poorly to acetaminophen
- Heavy bleeding rather than light spotting
- Fever, nausea, or vomiting alongside cramping
- Signs of ovarian hyperstimulation syndrome (OHSS), which can develop within one to two weeks of a trigger shot. Symptoms include rapid weight gain (more than about 2 pounds in 24 hours), severe bloating, shortness of breath, and decreased urination
Mild OHSS typically resolves on its own within a week, but severe cases need medical attention. If you used a trigger shot, pay attention to bloating and nausea in the days following your procedure.
When to Take a Pregnancy Test
Wait at least 14 days. Testing earlier is tempting but unreliable, especially if your cycle included a trigger shot containing hCG, the same hormone pregnancy tests detect. Depending on the dose, the trigger shot can take a full two weeks to clear your system. A test taken at day 8 or 10 could read positive simply because leftover hCG from the injection is still circulating, not because implantation occurred.
Most clinics schedule a blood test at the 14-day mark, which measures hCG levels more precisely than a home urine test. If you do take a home test, use it on day 14 or later and follow up with your clinic regardless of the result.
Realistic Expectations for Success
IUI success rates vary widely depending on age, the underlying fertility issue, and sperm quality. A commonly cited range is 10% to 20% per cycle. One recent study found a clinical pregnancy rate of about 32% per cycle when sperm quality was good (specifically, when the processed sample contained more than 5 million motile sperm), but a 0% rate when it fell below that threshold. Age is also a factor, with some research showing a noticeable decline in success after age 32.
These numbers mean that most IUI cycles don’t result in pregnancy on the first try. That’s not a sign something is wrong. Many couples go through three to six cycles before conceiving, and your doctor will reassess the approach if several cycles are unsuccessful. The two-week wait can feel like the longest stretch of your life, but doing what you can on the lifestyle front and then letting your body do its work is genuinely the best strategy.
