Periods during a pregnancy?

Stefani • Don Bon Lopez. 😍💍

Could it be possible? My breasts have been more tender, they feel extra heavy and they hurt all over. My periods are every month, sometimes I'm a couple of days late. But my belly has seem to look more bigger than usual, it doesn't even look like bloatness anymore. And my SO has also said I'm starting to waddle?... Could I possibly be pregnant, even though I have a monthly menstrual cycle?
