Does having a Sexually Transmitted Infection affect your pregnancy options?

Yes!

When considering your pregnancy options, it is important to know if you have a
Sexually Transmitted Infection. It is always best to be treated for a STI as soon as possible,
but if you are considering having an abortion, you MUST receive treatment prior to having that abortion procedure.

Women who have an untreated STI (like Chlamydia or Gonorrhea) are up to 25% more likely to develop
Pelvic Inflammatory Disease (PID) following an abortion procedure.
So, it is important to be tested for STIs prior to making any decisions about the outcome of your pregnancy.
