If you're planning a pregnancy while on semaglutide, the most useful date to know is the day of your last dose. Not the day you plan to start trying, and not the day a test turns positive. Semaglutide has a long half-life, about one week according to the prescribing information, so the drug lingers for weeks after the final injection. Semaglutide pregnancy planning starts with that calendar fact, because stopping the drug doesn't clear it out overnight.
Semaglutide stays in your body for weeks after the last dose. Here is how to map the timeline, the contraception plan, and the product checks before you try to conceive.
Why the washout clock starts before you stop caring about it
The US prescribing information for Ozempic and Wegovy advises discontinuing the drug at least two months before a planned pregnancy. That's the timing the label gives, and many people underestimate it. They count from the day they feel better, or from the day they decide to stop, when the relevant count begins at the last dose. Brazilian bulas can use different wording, so read the version attached to your own product and bring it to the appointment.
The washout window and your conception timing overlap, which makes the last dose date your reference point. If your final injection was on a Monday, count forward from that Monday. A positive test works differently. It arrives after conception has already happened, so it tells you where you are in the timeline, not what the drug was doing when it mattered most.
If your dose changed recently, keep that in mind too. The label describes several weeks before levels settle at steady state after a dose change, so a recent increase can shift the timeline your doctor chooses.

Contraception is the part of the conversation people tend to skip. Oral semaglutide, sold as Rybelsus, can affect how other oral medications are absorbed. Its label includes a drug interactions section with guidance on oral contraceptives, and that wording deserves a careful read before you assume anything about your current pill.
For most people, the safer default to discuss is continuing effective contraception during treatment and through the washout period. Your doctor can tell you which methods fit your health history and which ones the label or a professional guideline lists as options. Ask specifically whether your plan changes if you move from a pill to a non-oral method, and how long you should keep contraception going after your final dose.
The injectable and oral forms don't always carry identical instructions. Match your advice to the form you actually use, and compare the pregnancy and drug interaction sections of each label instead of relying on memory or a summary you read online.
