I’m on birth control and have been for about a year. I am only 14, and I know birth control is supposed to lessen my period, but I went on birth control last December…

…since May, I have been getting my period very lightly for like a day or I have missed it. Last weekend my boyfriend put it in up my butt, and his penis felt wet against my back, but he pulled it out really quickly. Then I gave him a handjob, he peed, and then we had sex. We had sex for about 30 seconds, and it wasn’t all the way in. He said he did not cum. He also told me when he ejaculates he does not pre-cum. I missed my period again, and I’m scared it is because I’m pregnant! I read about your boobs being swollen, darker, and they hurt, now that I think about it my one boob looks kind of swollen, darker, and hurts! It has only been a week since we had sex! Everyone is telling me my boob hurts because I’m paranoid! But could I be pregnant? Please get back to me ASAP! I’m freaking!

It’s important to note that the only way to 100% prevent STIs and unplanned pregnancy is to practice abstinence. Abstinence is when someone refrains from oral, anal, or vaginal sex. However, if you have been taking your birth control correctly and consistently, you will be up to 99% protected from pregnancy. If you have not been taking your birth control either on time or incorrectly, you could be at risk of pregnancy.

Your risk of pregnancy is lower when engaging in anal sex, but without use of a barrier method, like a condom, you are at risk of STI transmission.

Although your partner did not ejaculate inside of you, pre-cum is something that everyone with a penis does when arousal happens. Pre-cum—officially called pre-ejaculate—is a clear, sticky fluid released by the penis between the beginning of arousal and ejaculation.  Doctors believe that pre-ejaculate helps make the urethra and the vagina less acidic, allowing sperm to survive longer.  Some males release a small amount of pre-ejaculate; others may release quite a bit.

Although pre-ejaculate does not contain sperm when it is produced, it can pick up leftover sperm in the urethra. This means that pre-ejaculate can contain sperm when it leaves the body, creating a risk for pregnancy.  Pre-ejaculate can also transmit STIs. Because your partner urinated before having vaginal sex with you, there’s a small chance that there was any sperm left in the urethral tract, but it can be impossible to know for sure!

Depending on your method of birth control, irregular bleeding can be a common side effect. If you haven’t had a consistent period on your current method, you may want to talk with the medical provider who prescribed it to you. They will be able to help you figure out what may be going on with your body and possibly help you control those side effects!

There can be many symptoms of pregnancy, but those symptoms can be inconclusive. All of the symptoms that you’ve described can be signs of things other than pregnancy (like your period). The only way to know for sure if you’re pregnant is to take a test 2 weeks after your most recent sexual encounter.
