Concerns About Pregnancy After Incorrect Condom Use: What to Know

Reapplying a condom after it has been put on the wrong way?

On the night of July 2nd, I had sexual intercourse with my girlfriend.
The condom was put on inside out (it couldn't be rolled down), and I immediately turned it around and put it on correctly (I subconsciously used my finger to slightly wipe the tip that had touched the glans).
Since both of us were inexperienced (virgin male and female, both 21 years old), during penetration, I only inserted about half of the glans and did not go deeper.
There was no ejaculation afterward (I also checked the condom by filling it with water, and there were no leaks).
I took emergency contraception (Ella) two hours later.
My girlfriend's last menstrual period was around mid-May (her menstrual cycle is very irregular).
As of now, July 8th, her period has not yet arrived.
I would like to ask the doctor if the chances of pregnancy are high in this situation.
We are both very worried, and I would appreciate your guidance.

Hello, you should not be pregnant.
You can take a test to check, and if your period still hasn't arrived in a week, I recommend seeing a gynecologist.
Wishing you good health.

When it comes to concerns about pregnancy after incorrect condom use, it's important to understand a few key points regarding the mechanics of contraception, the timing of ovulation, and the effectiveness of emergency contraception.

Firstly, the scenario you described involves a condom being put on incorrectly but then being reversed and used correctly afterward. While this may seem concerning, the fact that you did not ejaculate during intercourse significantly reduces the likelihood of pregnancy. Sperm must be present in the vaginal canal for fertilization to occur, and since you did not ejaculate, the risk is considerably lower.

However, it’s important to note that pre-ejaculate fluid (pre-cum) can contain sperm, although the quantity is usually much lower than in ejaculate. If any pre-ejaculate came into contact with the vaginal area, there is a slight possibility of pregnancy, but this risk is generally considered low, especially given the circumstances you described.

You mentioned that your girlfriend has a history of irregular menstrual cycles, which can complicate the situation. Irregular cycles make it difficult to predict ovulation, which is the time when a woman is most fertile. If her last period was in mid-May and she has not had a period by early July, it’s possible that she could be experiencing a delay due to stress, hormonal fluctuations, or other factors unrelated to pregnancy.
Taking emergency contraception (like the "Yuzpe regimen" you mentioned) within two hours after the incident is a proactive step. Emergency contraceptive pills are most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but they can still be effective up to 5 days later. The effectiveness of these pills decreases the longer you wait, but since you took it promptly, it should have significantly reduced the risk of pregnancy.

If your girlfriend's period does not arrive within a week or so, it would be advisable for her to take a home pregnancy test. These tests are generally reliable and can provide peace of mind. If the test is positive, or if she continues to experience symptoms of pregnancy (such as nausea, breast tenderness, or fatigue), it would be prudent to consult a healthcare provider for further evaluation and guidance.

In summary, while there is a slight chance of pregnancy due to the circumstances you described, the risk is low, especially considering the use of emergency contraception. Irregular menstrual cycles can lead to anxiety about potential pregnancy, but they can also be influenced by various factors. Monitoring her menstrual cycle and taking a pregnancy test if her period does not arrive will provide clarity. If there are any further concerns, consulting with a healthcare professional can provide additional reassurance and support.
