More Info

When considering the likelihood of pregnancy occurring on the first day of your girlfriend's period, it's important to understand the menstrual cycle and the factors that influence ovulation and fertility.
Typically, a woman's menstrual cycle is divided into several phases: the menstrual phase (when bleeding occurs), the follicular phase (when the body prepares for ovulation), ovulation (when an egg is released), and the luteal phase (post-ovulation). The average cycle lasts about 28 days, but it can range from 21 to 35 days in healthy women. Ovulation usually occurs around the midpoint of the cycle, approximately 14 days before the next period starts.

In your case, since you mentioned that your girlfriend's period started in the morning and you had sexual intercourse in the afternoon, the chances of pregnancy are relatively low. This is because the first day of menstruation is generally considered to be a time when a woman is least fertile. However, there are exceptions to this rule, particularly if her cycle is shorter than average or if she has irregular cycles.
Using a condom significantly reduces the risk of pregnancy, provided it is used correctly and does not break or leak. You mentioned that you checked the condom after intercourse and found no leaks, which is a positive sign. However, it's essential to remember that no contraceptive method is 100% effective.
If your girlfriend's menstrual cycle is typically regular, the likelihood of her becoming pregnant from intercourse on the first day of her period is quite low. However, if her cycles are irregular or if she ovulates earlier than expected, there is a small chance of pregnancy. Sperm can survive in the female reproductive tract for up to five days, so if she were to ovulate shortly after her period, there could be a risk.

In terms of next steps, if your girlfriend is concerned about the possibility of pregnancy, she could consider taking a home pregnancy test if her period is late. Most home pregnancy tests are reliable and can detect pregnancy about a week after a missed period. If she is anxious about the situation, it may also be beneficial for her to consult a healthcare provider for further guidance and support.

In summary, while the risk of pregnancy from intercourse on the first day of menstruation is low, it is not entirely absent. The use of condoms adds a layer of protection, but if there are any concerns about potential pregnancy, taking a pregnancy test or consulting with a healthcare professional can provide clarity and peace of mind.
