True or false?

Question

I heard it was possible to continue periods while being pregnant, ofcourse maybe the period would last no more than 3 or 4 days and it would be a light flow. Another thing i heard is that you can be pregnant and not even know it until birth, something about the way the baby sits in your stomach. ANOTHER thing i heard is that heartburn can be a symptom of pregnancy. Is any of this true or am i just worrying i am pregnant for nothing? (By the way my period is 4 days late).

Answer

You cannot have a period, which is the shedding of your uterine lining where an egg would have implanted, when pregnant. But you can have bleeding, sometimes even lining up with the timing of your period, and mistake that for your period.
