2. Prevent an unwanted pregnancy.
Unless you’re ready for children, get emergency contraception. The most common are found in pill form.

The pills are about 75-89% effective in helping to prevent pregnancy and they’re not just effective the day after unprotected sex. “You can take it up to five days after this kind of an accident, but the earlier you get it the better,” says Dr. Hilda Hutcherson, an AOL Love & Sex Coach and author of Pleasure: A Woman's Guide to Getting the Sex You Want, Need, and Deserve.

Like any medication, emergency contraceptive pills can cause side effects, such as nausea or vomiting, your period may come earlier or later and be heavier or lighter than normal. If you get especially sick, which is rare, ask your doc about medications that help with motion sickness. You’ll need to keep the pills down for them to be effective.
