The abortion pill can be used up to 10 weeks of pregnancy, counted from the first day of your last menstrual period (70 days). The process itself involves two medications taken one to two days apart, with the most intense phase lasting several hours after the second pill.
The 10-Week Window
The FDA approved the abortion pill regimen for use through 10 weeks of gestation. That 10-week count starts from the first day of your last period, not from the date of conception. So if your last period started on March 1, you would have until roughly May 9 to use the pills.
If you’re unsure how far along you are, an ultrasound or a careful review of your menstrual history can clarify the timeline. The closer you are to that 10-week mark, the more important it is to act quickly, since each day counts. After 10 weeks, a procedural (surgical) abortion is typically the option offered instead.
How the Two Pills Work
The regimen uses two different medications taken in sequence. The first pill blocks the hormone progesterone, which the pregnancy needs to continue. On its own, this pill rarely causes noticeable symptoms beyond mild nausea in some people.
The second medication is taken 24 to 48 hours later. You place the tablets between your cheek and gum (buccally) or vaginally, depending on your provider’s instructions, and let them dissolve. This second pill triggers cramping and bleeding that expels the pregnancy tissue.
What the Active Phase Feels Like
After taking the second medication, most people begin experiencing cramps and bleeding within four to six hours. The heaviest bleeding and strongest cramping typically last only a few hours, though the overall process of passing tissue can take up to about 16 hours. During the intense window, cramps can be significantly stronger than a normal period. Pain medication (usually ibuprofen) helps, and many providers recommend having it ready before you take the second pill.
You’ll want to plan to be home or somewhere comfortable for at least the rest of that day. Most people find the worst is over within a single afternoon or evening, though some lighter cramping may continue into the next day.
Bleeding and Recovery Afterward
Light bleeding or spotting commonly continues for up to two weeks after the procedure, though the duration varies depending on how far along the pregnancy was. Some people see spotting taper off within a week, while others notice it off and on for the full two weeks. Heavy bleeding (soaking more than two thick pads per hour for two or more hours) is not typical after the initial expulsion phase and warrants a call to your provider.
Most people feel physically recovered within a few days and can return to work or normal activities the day after taking the second pill, though some prefer an extra day of rest. A follow-up appointment or at-home pregnancy test is usually scheduled one to two weeks later to confirm the abortion is complete.
Effectiveness Across the 10-Week Window
The combination regimen is highly effective, with success rates above 95% when used within the approved window. It works best at earlier gestational ages. The further along you are, the slightly higher the chance you may need a follow-up dose or a procedural abortion to complete the process. If the pills don’t fully work, your provider will discuss next steps, which usually involve a brief in-clinic procedure.
When Mifepristone Isn’t Available
In some situations, people use the second medication alone without the first pill. This misoprostol-only approach involves taking 800 micrograms every three hours until expulsion occurs, with three to four doses typically provided. It is less effective than the two-drug combination and generally involves more cramping and a longer process, but it remains an option where the first medication is unavailable.
Fertility Returns Quickly
Ovulation can resume as soon as two weeks after a medication abortion, meaning pregnancy is possible again before your next period even arrives. If you don’t want to become pregnant right away, starting contraception shortly after the abortion is important. Many providers will discuss birth control options at the same appointment where they prescribe the pills or at the follow-up visit.
