If a woman gets her period not pregnant? right? what is the difference between menstrual bleeding and implatation bleeding? thanks..

Difficult to tell: Bleeding patterns can vary from woman to woman. Most of the time it's difficult to tell the difference between a normal period and 1st trimester bleeding based solely on appearance. You should perform a home pregnancy test to see if you are pregnant. This is a quick and accurate way to distinguish between the two. If you are pregnant and bleeding, you should see your doctor immediately.
