Dear Unprotected Sex And Your Menstrual Cycle,

 

Your boyfriend having unprotected sex with someone else will in no way directly affect your menstrual cycle. However, there is a possible indirect way this could happen. Some STIs, especially left untreated, can negatively affect a woman’s reproductive system, including her menstrual cycle. Your boyfriend having unprotected sex with someone else and then having sexual contact with you would not directly impact your menstrual cycle in and of itself. But if he transmitted an STI when he had unprotected sex and then passed that STI onto you, it is possible that the STI could then affect your menstrual cycle.

 

If you are concerned about your menstrual cycle, that you may have transmitted an STI, or that you may be pregnant, FX recommends that you meet with a healthcare professional as soon as possible.

 

In response to your question, TeenHealthFX also wants you to think about the following:

 

  • Many teenage girls find that their periods do not always come at the same time each month or that there is variation in how heavy their periods are. This is common experience since a girl’s period is often irregular for the first few years of menstruation.

 

  • Menstrual cycles can be impacted by other factors such as not eating enough, over-exercising, and feeling stressed.

 

  • If you and your boyfriend had unprotected sex or the two of you had any problems with your birth control method(s), and you have not gotten your period since that time, it is possible that you are pregnant. If you are worried you might be pregnant, please schedule an appointment with a healthcare professional as soon as possible.

 

  • If your boyfriend had unprotected sex with someone else and then had any kind of sexual contact with you, it is possible that an STI was transmitted. Keep in mind that there are certain STIs where people do not see any signs or symptoms right away that they are infected with an STI and can, therefore, pass on that STI unknowingly. FX strongly recommends that your boyfriend speak to a healthcare professional about getting tested for various STIs (his doctor can advise him on this), and that you get tested as well if you have had any sexual contact with him since he had unprotected sex with another partner.

 

  • Having unprotected sex puts people at risk for unwanted pregnancies and transmitting STIs. FX strongly recommends that you and boyfriend practice safer sex by using a condom and a back-up method of birth control (such as the pill or patch) each time you have sex with any sexual partners.

If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-6475 for an appointment or contact your local teen health center or Planned Parenthood.
