Can I get pregnant?


Hello doctor, I had unprotected intercourse with my boyfriend yesterday.
He was wearing a condom at first but then took it off.
He only penetrated a few times before withdrawing.
The app on my phone predicted my ovulation day, but my menstrual cycle is irregular.
I didn't take emergency contraception afterward.
What is the likelihood of getting pregnant in this situation? My period just ended on January 6th.

What you need is not medical advice but rather a refresher on sexual education.
For such questions, it is recommended to refer to the National Health Administration's "Sexual Happiness e-Learning" or the Obstetrics and Gynecology Society's "Consultation for Adolescent Contraceptive Guidelines" at http://goo.gl/dc6PfW.

Hello, the questioner: Engaging in sexual intercourse without ejaculation still carries a risk of pregnancy, as pre-ejaculatory fluid may contain sperm.
It is advisable to take a pregnancy test if your period is more than a week late.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info


When it comes to assessing the risk of pregnancy after unprotected intercourse, several factors need to be considered, including the timing of the menstrual cycle, the nature of the sexual activity, and the use of contraceptive methods.

In your case, you mentioned that you had unprotected intercourse with your boyfriend, where he initially used a condom but later removed it. You also noted that he did not ejaculate inside you. While the withdrawal method (pulling out) can reduce the risk of pregnancy, it is not a reliable form of contraception. Pre-ejaculate fluid (pre-cum) can contain sperm, and if there was any sperm present, there is a possibility of pregnancy.

You indicated that your menstrual cycle is irregular and that you recently finished your period (from December 31 to January 6). The timing of ovulation is crucial in determining the risk of pregnancy. Ovulation typically occurs about 14 days before the start of your next period, but this can vary significantly, especially in individuals with irregular cycles. If your app predicted ovulation around the time of intercourse, it could increase the risk of pregnancy, as sperm can survive in the female reproductive tract for up to five days.

Since you did not take emergency contraception (the "morning-after pill") after the incident, it is important to monitor your body for any signs of pregnancy. Symptoms such as missed periods, breast tenderness, nausea, or unusual fatigue can indicate pregnancy, but these symptoms can also be related to other factors, including hormonal changes or stress.

Given your situation, here are some recommendations:
1. Wait for Your Next Period: If your period is late by a week or more, consider taking a home pregnancy test. These tests are generally accurate and can provide you with a clear answer.

2. Consider Emergency Contraception: If you are still within the window (typically up to 72-120 hours after unprotected intercourse) for taking emergency contraception, it may be worth considering. This can significantly reduce the risk of pregnancy.

3. Consult a Healthcare Provider: If you have ongoing concerns about your menstrual cycle or the risk of pregnancy, it may be beneficial to speak with a healthcare provider. They can offer personalized advice and may suggest hormonal contraceptives to help regulate your cycle and prevent future unintended pregnancies.

4. Track Your Cycle: Keeping a detailed record of your menstrual cycle can help you better understand your ovulation patterns and fertility windows. This can be useful for future sexual encounters and for making informed decisions about contraception.

In conclusion, while the risk of pregnancy exists due to the nature of the sexual activity and the timing in relation to your menstrual cycle, it is difficult to quantify without further information. Monitoring your cycle and being aware of your body’s signals will be key in managing your reproductive health. If you have any doubts or experience unusual symptoms, do not hesitate to seek medical advice.
