Can I get pregnant?

Hello, doctor.
On April 28th, around 3 PM, I had unprotected intercourse with my girlfriend for less than a minute before withdrawing.
I'm concerned about the possibility of pre-ejaculate fluid on the glans, and I'm wondering what the chances of pregnancy are.
My girlfriend's period started on April 16th and ended on April 20th.
On April 28th, she had vaginal discharge, and I'm worried that there might have been pre-ejaculate fluid that I wasn't aware of.
My girlfriend hasn't taken any pre- or post-coital contraception.
Could you please help me with this?

Hello: From what I see, the chances of conception are low in your situation, but there are always exceptions.
If you are really concerned, you can still take emergency contraception within 48 hours.
You might want to consider that.
(The time of potential conception was on the 13th day of your cycle, which is considered a fertile period, but since there was no ejaculation and you are only worried about possible unintentional pre-ejaculation, theoretically, the chances of conception are low.)

When it comes to assessing pregnancy risks after unprotected intercourse, there are several factors to consider. In your case, you had unprotected intercourse on April 28, shortly after your girlfriend's menstrual period ended on April 20. Understanding the timing of ovulation and the nature of sperm can help clarify the risk of pregnancy.

1. Understanding the Menstrual Cycle: A typical menstrual cycle lasts about 28 days, but it can vary from person to person. Ovulation typically occurs around 14 days before the start of the next menstrual period. Since your girlfriend's last period started on April 16 and ended on April 20, she would likely ovulate around May 1 (assuming a 28-day cycle). This means that the risk of pregnancy from intercourse on April 28 is relatively low, as it is just a few days before her expected ovulation.

2. Sperm Viability: Sperm can survive in the female reproductive tract for up to five days under optimal conditions. However, since you had intercourse just a few days before her expected ovulation, there is still a possibility that sperm could be present when she ovulates, which could lead to pregnancy.

3. Pre-ejaculate Fluid: You mentioned concerns about pre-ejaculate fluid (pre-cum). This fluid can contain sperm, although the concentration is generally lower than in ejaculate. If there was any pre-ejaculate fluid on the vaginal opening or if it was introduced during intercourse, there is a potential risk for pregnancy, albeit lower than with full ejaculation.

4. Timing and Symptoms: Since your girlfriend's next expected period would be around May 16, you should monitor for any signs of pregnancy. Common early signs include missed periods, breast tenderness, nausea, and fatigue. If her period is late, it would be advisable for her to take a home pregnancy test for confirmation.

5. Emergency Contraception: Since your girlfriend did not take any form of emergency contraception after the intercourse, it's important to understand that the effectiveness of such methods decreases significantly the longer you wait after unprotected intercourse. Ideally, emergency contraception should be taken within 72 hours for maximum effectiveness.

6. Consulting a Healthcare Provider: If there are any concerns about potential pregnancy or if your girlfriend experiences unusual symptoms, it is best to consult a healthcare provider. They can offer guidance on pregnancy testing and discuss options for contraception moving forward.

In summary, while the risk of pregnancy from the intercourse on April 28 is relatively low given the timing in relation to her menstrual cycle, it is not zero. Monitoring her menstrual cycle and being aware of any early pregnancy symptoms will be crucial in the coming weeks. If there are any uncertainties or if her period is late, a pregnancy test would be the next logical step. Additionally, discussing contraception options with a healthcare provider can help prevent similar concerns in the future.
