When it comes to understanding the chances of pregnancy after protected intercourse, it's important to consider several factors, including the timing of ovulation, the effectiveness of the contraceptive method used, and the nature of the sexual activity.

In your case, you mentioned that you had sexual intercourse on March 2nd with a condom, and that your boyfriend withdrew before ejaculation. This is a crucial point because using a condom correctly significantly reduces the risk of pregnancy. Condoms have a typical effectiveness rate of about 85-98% when used properly, meaning that while there is still a small chance of failure, it is considerably low. The fact that he withdrew before ejaculation further decreases the likelihood of sperm entering the vagina.

You also mentioned that you had sexual activity on March 4th, which involved no penetration but included some form of external contact with semen. While the risk of pregnancy from this type of activity is generally low, it is not entirely absent. Sperm can potentially be transferred from the external genitalia to the vaginal area, especially if there was any direct contact with semen. However, the chances of pregnancy occurring from this scenario are significantly lower compared to direct vaginal intercourse.

Regarding your ovulation date of March 1st, it is important to note that the fertile window typically spans from about five days before ovulation to one day after. This means that if you ovulated on March 1st, your most fertile days would have been from February 25th to March 2nd. Since you had intercourse on March 2nd, you were at the tail end of your fertile window, which means there was a possibility of conception, but it is still relatively low given the protective measures you took.

To summarize, the chances of pregnancy in your situation are low, particularly due to the use of a condom and the withdrawal method. However, there is still a slight risk associated with the external contact of semen. If you are concerned about the possibility of pregnancy, consider taking a home pregnancy test if your period is late or if you experience any unusual symptoms.
In the future, if you want to further reduce the risk of unintended pregnancy, you might consider discussing additional contraceptive methods with your healthcare provider. Options such as hormonal birth control, intrauterine devices (IUDs), or other long-acting reversible contraceptives can provide more reliable protection against pregnancy.

Lastly, if you have any concerns about your menstrual cycle or reproductive health, it is always a good idea to consult with a healthcare professional who can provide personalized advice based on your specific circumstances.
