Can you still be pregnant if got your period 10 days before were supposed to get it and was very light lasted 3 days?

Yes. It's possible to be pregnant even if you have a period. This can happen for a variety of reasons, including:

* Implantation bleeding: This is light bleeding that can occur when the fertilized egg implants in the uterus. Implantation bleeding typically occurs within 1-2 weeks after ovulation, but it can sometimes happen earlier or later.

* Breakthrough bleeding: This is light bleeding that can occur between periods. Breakthrough bleeding is often caused by changes in hormone levels.

* A miscarriage: This is the loss of a pregnancy before 20 weeks of gestation. Miscarriages can often be confused with periods, as they can cause similar symptoms, such as bleeding, cramping, and back pain.

If you're concerned that you might be pregnant, even if you've had a period, it's important to take a pregnancy test. Pregnancy tests can be purchased at most drug stores and are easy to use. If the pregnancy test is positive, you should make an appointment with your doctor to confirm the pregnancy and discuss your options.
