Probability and Secretion


Hello: I got my period on June 16 (I had been taking oral contraceptives but am not currently using them).
I had intercourse on June 26, and my boyfriend used a condom throughout.
What is the likelihood of pregnancy in this situation? Recently, I've noticed an increase in discharge; is this normal?

Mi, 10~19 year old female. Ask Date: 2010/07/07

Dr. Lü Lizheng reply Obstetrics and Gynecology


Dear Mi: Hello, if your boyfriend has used condoms consistently, the likelihood of pregnancy is low.
Increased discharge may indicate ovulation or elevated hormone levels, which will naturally decrease over time.
However, if you experience any foul odor, itching in the vulva, or changes in color, it may indicate vaginitis, and you should seek medical treatment.
Wishing you safety and health.
Sincerely, Dr.
Lu Li-Cheng, Director of the Department of Obstetrics and Gynecology, Taoyuan Hospital, Ministry of Health and Welfare.

More Info


When considering the risks of pregnancy after unprotected intercourse, it is important to understand the timing of ovulation and the effectiveness of contraceptive methods used. In your case, you mentioned that your last menstrual period started on June 16 and that you had intercourse on June 26. Assuming a typical menstrual cycle of about 28 days, ovulation would likely occur around June 30, which is approximately 14 days after the start of your last period.
If your boyfriend used a condom during intercourse, this significantly reduces the risk of pregnancy, as condoms are generally effective when used correctly. However, no contraceptive method is 100% effective, and there is always a small chance of pregnancy even with proper condom use due to potential breakage or slippage.
Regarding your concern about increased vaginal discharge, it is common for women to experience changes in vaginal discharge throughout their menstrual cycle, especially around ovulation. Increased discharge can be a normal physiological response and is often clear or slightly cloudy. However, if the discharge has a strong odor, is accompanied by itching, or changes in color (such as becoming yellow or green), it could indicate an infection, and you should consult a healthcare provider.

In summary, while the likelihood of pregnancy in your situation is low due to the use of a condom, it is not impossible. If you have concerns about pregnancy or notice any unusual symptoms, consider taking a home pregnancy test if your period is late or consult with a healthcare professional for further evaluation.
Additionally, if you are experiencing any anxiety about potential pregnancy or changes in your body, it is always a good idea to seek advice from a healthcare provider who can offer personalized guidance based on your health history and current situation. They can also provide information on contraceptive options if you are considering resuming birth control methods in the future.
