Other concerns

• You may get a headache, an upset stomach, or belly pain after you take this medicine.
  • If you need to, take an over-the-counter pain medicine such as acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or naproxen (Aleve). Read and follow all instructions on the label.
  • For belly pain, use a hot water bottle or a heating pad set on low.
• You may have light bleeding (spotting) in the week after you take the pill.
• Your next period may start a few days earlier or later than you expect. If your period is more than 7 days late, or if it is lighter than you expect, get a pregnancy test.
• The pill won't protect you for the rest of your cycle. Use condoms or another barrier method of birth control until you start your period. If you use a hormone method, such as birth control pills, the vaginal ring, or the patch, wait 5 days after you take ulipristal before you use them again. When you restart your hormone method of birth control, also use condoms for the first 14 days.
• The pill won't prevent sexually transmitted infections (STIs). If you're worried that you might have been exposed to an STI, talk to your doctor.
