Quick answer:
GLP-1s are not for pregnancy — stop semaglutide ~2 months before conceiving (tirzepatide ~1 month). But they restore fertility powerfully: 'Ozempic babies' happen because weight loss reactivates ovulation. Pregnant on a GLP-1? Stop, call your OB — most documented cases ended healthy. Compare GLP-1 programs.
Why GLP-1s make people unexpectedly fertile
'Ozempic babies' — the documented wave of unplanned pregnancies on these drugs — have a boring explanation: biology working. Obesity-related anovulation and PCOS often mean years without reliable ovulation; 5-10% weight loss frequently restores it, sometimes within months. Add that tirzepatide can weaken the pill and you get the viral headlines. The fertility effect is real enough that responsible prescribers now counsel on contraception at initiation — see GLP-1 and birth control and GLP-1 for PCOS.
Planning pregnancy: the washout rule
| Medication | Stop before conceiving |
|---|---|
| Semaglutide (Ozempic, Wegovy) | ~2 months |
| Tirzepatide (Mounjaro, Zepbound) | ~1 month |
| Reason | Long half-lives need weeks to clear |
The washout matters because the drugs aren't recommended in pregnancy — animal data showed fetal harm at human-relevant doses, and intentional weight loss during pregnancy isn't advised regardless. A planned stop also beats an emergency stop: you finish a treatment arc, then conceive, rather than quitting mid-titration.
If pregnancy finds you on the drug
Stop, call your OB, breathe. Human outcome data is limited but reassuring — most reported first-trimester GLP-1 exposures have had healthy outcomes, and exposure isn't a sentence. What changes: the drug stops immediately, early ultrasound monitoring is standard, and the pregnancy proceeds without the medication. Registries now track GLP-1 pregnancies to build real human data.
Breastfeeding too
Same caution applies postpartum — GLP-1s aren't recommended while breastfeeding (unknown transfer to milk, plus nutritional demands of nursing make appetite suppression a bad idea). Restarting is typically deferred until weaning. More: GLP-1 and breastfeeding.
Planning pregnancy? Time the washout

Compare programsFrequently asked questions
Can you take Ozempic while pregnant?
No — not recommended; animal data showed fetal harm. Pregnant on it? Stop and call your OB — most documented exposures ended healthy.
How long before pregnancy should I stop Ozempic?
~2 months for semaglutide, ~1 month for tirzepatide — long half-lives need real clearance time.
What are 'Ozempic babies'?
Unplanned pregnancies on GLP-1 — weight loss restores ovulation, and tirzepatide can weaken the pill. Contraception counseling is now standard.
What happens if I get pregnant on Ozempic?
Stop immediately, tell your OB, expect early monitoring. Most reported cases had healthy outcomes — exposure isn't a sentence, but the drug comes off.
Does Ozempic increase fertility?
Indirectly and powerfully — restored ovulation after weight loss surprises women who assumed infertility. Plan accordingly either way.
Bottom line
GLP-1s and pregnancy don't mix — but the road there needs explicit planning either way: contraception if pregnancy isn't the goal, a 1-2 month washout if it is. Compare programs. Related: GLP-1 and birth control, GLP-1 and pregnancy, GLP-1 and breastfeeding.
