Probability of conception
My last menstrual period was from February 19 to February 25, and my cycle is very regular.
I had intimate contact on February 26 and February 28, using a condom, with only friction at the vaginal opening and external ejaculation.
Is there a possibility of pregnancy in this situation? Thank you.

Hello, the chances are low, but it's not advisable to rely on the safe period.
It's better to take preventive measures for contraception before engaging in sexual activity.
If your period is more than a week late, it is recommended to see a gynecologist.
Wishing you good health.

More Info
When considering the possibility of pregnancy from friction and withdrawal during your menstrual cycle, it's essential to understand the mechanics of conception and the timing of ovulation.
Firstly, the menstrual cycle typically lasts about 28 days, but it can vary from person to person. Ovulation usually occurs around the midpoint of the cycle, approximately 14 days before the start of the next period. In your case, if your last menstrual period started on February 19 and lasted until February 25, you would likely ovulate around March 5. The days leading up to and including ovulation are when you are most fertile.
Now, regarding the intimate activities you described on February 26 and February 28, it's important to note that while you used a condom and practiced withdrawal, there is still a risk of pregnancy. Pre-ejaculate fluid (pre-cum) can contain sperm, and even if you did not ejaculate inside the vagina, any sperm present in the pre-ejaculate can potentially lead to pregnancy if it comes into contact with the vaginal canal.
Friction alone, without ejaculation, typically poses a lower risk of pregnancy compared to direct ejaculation inside the vagina. However, the risk is not entirely eliminated, especially if there is any sperm present from pre-ejaculate. Additionally, sperm can survive in the female reproductive tract for up to five days, which means that if you were to ovulate shortly after your intimate activities, there could be a chance of conception.
Given your regular menstrual cycle, if you are concerned about the possibility of pregnancy, it would be wise to monitor for any signs of pregnancy, such as a missed period, nausea, or breast tenderness. If your period is late, taking a home pregnancy test can provide clarity.
In summary, while the risk of pregnancy from friction and withdrawal is lower than with unprotected intercourse, it is not zero. If you are actively trying to avoid pregnancy, consider using more reliable forms of contraception, such as hormonal birth control or intrauterine devices (IUDs), which can provide more effective prevention against unintended pregnancy. If you have further concerns or questions about your reproductive health, consulting with a healthcare provider can provide personalized advice and options based on your specific circumstances.
