Period while pregnant ?!

Can you be pregnant & still get your period? Or " bleeding " ?? My friend she is due in Feb said for two months she has hers before she found out she was pregnant. 
I was just wondering cause I've been having symptoms.. Even after I " had my period "
Or bleeding. Whatever you wanna call it. My boyfriend thinks I am pregnant. Should I take a test? Or should we keep trying anyways just in case I'm not? 
Please let me know, thanks (:
