Can you be pregnant a week before your period and still have period?

It's impossible to be pregnant a week before your period and still have a period. Here's why:

* The menstrual cycle: A period occurs when the lining of the uterus sheds if a fertilized egg doesn't implant. This process takes about 14 days after ovulation.

* Implantation: For pregnancy to occur, a fertilized egg needs to implant in the uterine lining. This usually happens around 6-12 days after ovulation.

* Timeframe: If you're pregnant, ovulation has already occurred, and implantation is happening or has already happened. You wouldn't have a period.

What you might be experiencing:

* Irregular periods: Some women have irregular periods, making it harder to pinpoint ovulation and track their cycle.

* Implantation bleeding: Some women experience light bleeding or spotting around the time of implantation, which can be mistaken for a period.

If you have any concerns about your cycle or think you might be pregnant, the best thing to do is:

* Take a pregnancy test: Home pregnancy tests are highly accurate.

* Consult a doctor: They can help you determine if you are pregnant, rule out other causes of bleeding, and provide personalized guidance.
