Can I get pregnant?

Having unprotected intercourse on the first day of your girlfriend's menstrual period carries a low risk of pregnancy, especially if her menstrual cycle is approximately 28 days and lasts for 7 days.
However, it is still possible for sperm to survive in the female reproductive tract for several days, and if she has a shorter cycle or ovulates early, there is a chance of conception.
It is always advisable to use protection to prevent unintended pregnancies and sexually transmitted infections.

When it comes to the possibility of getting pregnant from unprotected sex on the first day of a menstrual period, the answer is generally no, but there are important nuances to consider.
A typical menstrual cycle lasts about 28 days, but it can vary from person to person. Ovulation, which is when an egg is released from the ovary, usually occurs around 14 days before the start of the next period. Sperm can live inside a woman's reproductive tract for up to five days, which means that if a woman has a shorter cycle (for example, 21 days), she could potentially ovulate shortly after her period ends. In such cases, having unprotected sex during menstruation could lead to pregnancy if ovulation occurs soon after.

However, for a woman with a regular 28-day cycle, having unprotected sex on the first day of her period is typically considered low-risk for pregnancy. This is because ovulation is not expected to occur until around day 14 of the cycle, and the chances of sperm surviving long enough to fertilize an egg are slim.
That said, there are several factors that can influence this situation:
1. Cycle Variability: Not all women have a perfectly regular cycle. Stress, illness, hormonal imbalances, and other factors can cause ovulation to occur earlier or later than expected. If a woman has a shorter cycle or irregular cycles, the risk of pregnancy increases.

2. Sperm Viability: Sperm can survive in the female reproductive tract for several days. If a woman has a shorter cycle and ovulates soon after her period, there is a possibility that sperm from intercourse during menstruation could still be viable when ovulation occurs.

3. Misinterpretation of Menstrual Flow: Sometimes, what a woman perceives as the first day of her period may actually be light bleeding or spotting that is not part of her menstrual cycle. If this is the case, and she is actually nearing ovulation, the risk of pregnancy could be higher.

4. Contraceptive Methods: If a couple is not ready for a pregnancy, it is always advisable to use reliable contraception, even during menstruation.
In conclusion, while the likelihood of getting pregnant from unprotected sex on the first day of a period is low for women with a regular 28-day cycle, it is not impossible. It is essential for individuals to understand their own cycles and consider using contraception to avoid unintended pregnancies. If there are concerns about potential pregnancy after unprotected sex, taking a pregnancy test or consulting with a healthcare provider can provide clarity and guidance.
