Sexual intercourse


I noticed redness and swelling on my labia about three to four days after having unprotected sexual intercourse.
There are small, flesh-colored bumps, and while it itches, the discharge has increased but does not have any unusual odor or color.
The next day, I noticed similar symptoms near my anal area.
Is this inflammation or a sexually transmitted infection (STI)?
Additionally, I took emergency contraception (the type that is taken in two doses, morning and evening, over three days) right after the intercourse.
However, I am concerned because my period usually comes a few days after taking it, but this time it has been three days with no signs.
Normally, my menstrual cycle is approaching as well.
Is the type of emergency contraception I took meant to induce menstruation or to prevent fertilization? What is the likelihood of pregnancy in my case? If I am pregnant, would I need to pay out of pocket for RU-486 at the hospital? (I am an adult.)

1.
In terms of sexually transmitted infections, it is also an inflammation, so it is best for you to see a gynecologist for an examination.
2.
Most emergency contraceptive pills are hormonal medications that induce menstruation; the method of administration and outcomes vary depending on the ingredients.
3.
Mifepristone (Ru-486) is not covered by health insurance and is unrelated to the patient's age.

More Info


After engaging in unprotected sexual activity, it's common to experience a range of physical and emotional responses. Your symptoms, including redness and swelling of the labia, as well as the presence of small bumps, could indicate a few different possibilities. These symptoms may suggest a mild irritation or inflammation, possibly due to friction or an allergic reaction to a product used during sexual activity. However, they could also be signs of a sexually transmitted infection (STI), especially if accompanied by itching or unusual discharge. It's crucial to consult a healthcare professional for a proper diagnosis and treatment.

Regarding your concerns about emergency contraception, it’s important to understand how these medications work. The type of emergency contraception you mentioned, which is taken in multiple doses over a few days, is designed to prevent ovulation and may also alter the uterine lining to prevent implantation of a fertilized egg. However, it is not intended to terminate an existing pregnancy. If you took the emergency contraception soon after the unprotected intercourse, the likelihood of preventing pregnancy is generally high, especially if taken within 72 hours. However, the effectiveness decreases the longer you wait.

As for your menstrual cycle, it’s not unusual for it to be delayed after taking emergency contraception. Hormonal fluctuations caused by the medication can lead to changes in your cycle, including delayed menstruation. If your period does not arrive within a week of when you expect it, it would be advisable to take a pregnancy test to confirm whether or not you are pregnant.

If you find out that you are pregnant and are considering medical abortion, the medication RU-486 (mifepristone) is typically prescribed in a clinical setting. The cost and availability can vary depending on your location and healthcare provider. It’s essential to consult with a healthcare professional for guidance on the options available to you, as they can provide the necessary support and information regarding the process.

In summary, your symptoms warrant a visit to a healthcare provider for evaluation, especially to rule out any STIs or other infections. Additionally, while emergency contraception is effective, it can cause temporary changes in your menstrual cycle. If you have any further concerns about your reproductive health or potential pregnancy, seeking professional medical advice is the best course of action.
