Post-Coital Contraception: Confirming Pregnancy and Monitoring Symptoms - Obstetrics and Gynecology

Emergency contraception


On November 8, during my girlfriend's menstrual period, we had intercourse, and there was a noticeable amount of bleeding.
We did not use any protection, and I ejaculated inside her.
I am worried about the possibility of pregnancy, so I took emergency contraception the next day.
How can we confirm if she is pregnant afterward, and what symptoms might occur in the following days? I later found out that this could potentially lead to vaginal inflammation.
How should we monitor for that?

Dr. Lü Lizheng reply Obstetrics and Gynecology


The possibility of pregnancy is low.
You can take a pregnancy test 18 days after sexual intercourse to confirm whether you are pregnant.
If there is vaginal inflammation, possible symptoms include increased discharge, discomfort in the genital area (itching or pain), or an unpleasant odor from the genital area.
Sincerely, Dr.

More Info


When it comes to post-coital contraception and confirming pregnancy, there are several important steps and considerations to keep in mind. After having unprotected intercourse, especially during the fertile window, taking emergency contraception (like the morning-after pill) is a common and effective way to prevent pregnancy. Since you mentioned that your girlfriend took the emergency contraceptive pill the day after intercourse, this is a proactive step to reduce the risk of pregnancy.


Confirming Pregnancy
To confirm whether your girlfriend is pregnant after taking emergency contraception, the following steps can be taken:
1. Wait for the Next Menstrual Cycle: Emergency contraception can cause changes in the menstrual cycle, including delaying the next period. It’s important to wait until the expected date of her next period to see if it arrives. If her period is late by a week or more, it would be advisable to take a home pregnancy test.

2. Home Pregnancy Test: Home pregnancy tests are widely available and can detect the hormone hCG (human chorionic gonadotropin) in urine. For the most accurate result, it’s best to take the test first thing in the morning when urine concentration is highest.

3. Blood Test: If there is uncertainty or if the home test is positive, a healthcare provider can perform a blood test to confirm pregnancy. Blood tests can detect pregnancy earlier than urine tests and provide quantitative results.


Monitoring Symptoms
After taking emergency contraception, your girlfriend may experience some side effects, which can include:
- Nausea or Vomiting: Some women may feel nauseous after taking the pill.

- Fatigue: Feeling tired is a common side effect.

- Breast Tenderness: Hormonal changes can lead to breast sensitivity.

- Changes in Menstrual Cycle: As mentioned, her next period may be delayed, earlier, or may be lighter or heavier than usual.


Signs of Potential Issues
While emergency contraception is generally safe, it can sometimes lead to side effects or complications. If your girlfriend experiences any of the following symptoms, it may be a sign to seek medical attention:
- Severe Abdominal Pain: This could indicate an ectopic pregnancy or other complications.

- Heavy Bleeding: If she experiences heavy bleeding that soaks through a pad or tampon in an hour, it’s important to seek medical help.

- Fever or Chills: These could indicate an infection.

- Persistent Nausea or Vomiting: If these symptoms are severe and do not improve, it may be worth consulting a healthcare provider.


Vaginal Inflammation
Regarding your concern about potential vaginal inflammation, it’s important to monitor for signs such as:
- Itching or Burning Sensation: This could indicate an infection.

- Unusual Discharge: Changes in color, consistency, or odor of vaginal discharge can be a sign of an infection.

- Pain During Intercourse: If she experiences discomfort during sex, it may warrant further investigation.

If any of these symptoms occur, it’s advisable for her to see a healthcare provider for evaluation and treatment.


Conclusion
In summary, after taking emergency contraception, the best way to confirm pregnancy is to wait for the next menstrual cycle and use a home pregnancy test if her period is late. Monitoring for side effects and symptoms is also crucial. If any concerning symptoms arise, seeking medical advice is important for both her health and peace of mind. Always remember that open communication with your partner about these issues is key to navigating this situation together.
