My boyfriend and I had sex last night and used a condom. After he ejaculated he pulled out but forgot to hold the base of the condom as he did so and the condom stayed inside of me. I pulled it out but I am worried that something could have slipped in. I’m not expecting my period for another 19 days but I’m worried I am pregnant. What is my best option to be sure I am not pregnant?

Oops! You’re right – this is a great example of why it’s important to hold on to the base of the condom when pulling the penis out. If a condom slips off inside your vagina, semen can spill out and cause pregnancy.

Anytime a condom slips off, breaks, or tears after ejaculation has happened, and you are NOT currently on another form of birth control (like the pill, ring, patch, implant, or IUD), the best way to prevent pregnancy is to take emergency contraception, AKA the morning-after pill. You can use emergency contraception up to five days (120 hours) after unprotected sex.

You can get one type of morning-after pill called Plan B One-Step over-the-counter (without a prescription) at drugstores, no matter how old you are. Plan B One-Step works better the sooner you take it after unprotected sex, so get it as fast as possible. Other types of emergency contraception require a visit to a doctor, nurse, or other health care provider. You can also get it from Planned Parenthood health centers.

If you only use condoms for birth control, you might want to keep emergency contraception around to be prepared if something like this happens again. Even better? Think about going on a more long term form of birth control. Check out a quiz to help find the best one for you here.
