Your first period after the Depo shot can take a while. It often comes 6 to 12 months after your last injection, and some people wait longer. That’s the expected pattern for Depo-Provera, and it doesn’t depend on how long you used it.
This guide is about the Depo shot, sold as Depo-Provera, Depo-SubQ Provera 104 and, in the UK, Sayana Press. It covers two different questions. The first part is about your period after stopping. The last part is about bleeding while you’re still getting the shot.
When will I get my first period after the Depo shot?
Each shot is given every 13 weeks, according to the FDA label. The hormone keeps ovulation switched off well past that date. Your period only comes once you ovulate again, about two weeks later.
In the label’s studies, the median time to conception was 10 months after the last shot, with a range of 4 to 31 months. It didn’t depend on how long people had used the shot. Periods come back on roughly the same clock. The NHS says fertility can take up to a year to return.
| Since last shot | What’s usual |
|---|---|
| Up to 13 weeks | The shot is still working. No period is expected. |
| 3 to 6 months | Some people get a period. Most are still waiting, and that’s normal. |
| 6 to 12 months | The usual time for periods to come back. The label’s median time to conception is 10 months. |
| Over a year | Still within the range seen in studies, but see a doctor now rather than keep waiting. |
No period after the Depo shot wore off
This is the most common worry, and usually nothing is wrong. The shot “wears off” for pregnancy protection at about 13 weeks, but your ovaries can take many more months to restart. No period six or nine months after your last shot is normal for Depo.
Take a pregnancy test if you’ve had sex without another method. You can ovulate and get pregnant before you ever see a period, so “no period yet” doesn’t rule it out. The NHS says to test at least 21 days after sex when you don’t know when a period is due.
See a doctor if a year has passed since your last shot with no period, or sooner if you’re trying to get pregnant. Tell them you were on Depo, because it changes how long a gap counts as normal.
What is the first period after Depo like?
It’s often not like your old periods. The first one can be heavier or more painful, because the lining had been kept thin and now builds up again. It can also start with brown spotting for a day or two. Brown blood is older blood that took longer to leave, and it’s common at the start and end of any period.
The next few cycles may come at odd intervals before they settle. A gap of 40 days, then 30, then 33 is normal while the cycle settles. Our guide to periods after stopping birth control covers that settling phase for every method.
Heavy has a limit, though. Soaking a pad or tampon every hour for more than two hours in a row, or a period past 7 days, is worth a doctor’s visit. Our guide to a period that lasts too long says how soon.
Can I get pregnant before my first period after Depo?
Yes. Ovulation comes first and the period follows about two weeks later. If you got pregnant at that first ovulation, the first period never arrives.
If you don’t want to be pregnant, start another method on the day your next shot would have been due. If you do, the slow return is the main thing to plan around. The Cleveland Clinic says it takes about 10 months on average to conceive after the last injection, so some people stop the shot a year before they want to start trying.
Bleeding while you’re on the Depo shot
Changes to your period are the most common side effect. The NHS lists periods stopping, coming irregularly or lasting longer. In the FDA label’s studies, 57% of users had irregular bleeding or spotting at 12 months, and 32% at 24 months.
It tends to go one way. After the first shot, spotting on and off for weeks is common, and so is a period that won’t stop for two or three weeks. With each shot, fewer people bleed and more have no period at all. By 12 months, 55% had none, and by 24 months, 68%.
No period while on Depo isn’t a sign of a problem, and it doesn’t mean you’re pregnant if you’ve had every shot on time. Bleeding that’s very heavy, or that keeps going without easing, is different. The FDA label tells doctors to look for another cause in that case, so book a visit. A late shot, more than 13 weeks after the last one, also needs a pregnancy test first.
Keeping track in Plum
Plum, a period tracker app for iPhone, lets you add the shot as your birth control method. It can remind you one, three or seven days before the next dose is due. While a hormonal method is on, Plum warns that its period predictions are less reliable and hides ovulation and the fertile window by default.
When you stop, remove the method in Plum’s birth control settings. Then log any spotting on its own, so it doesn’t count as a period, and log the first real period when it comes. Once you have a few periods logged, Plum predicts from those dates.
