Let’s talk “period” while four weeks pregnant?

I need people who have experienced this also people with endometriosis. I am almost five weeks pregnant, yesterday I got the worst pain in my lower abdomen and last night bleeding. It has gone into today quite a lot of blood and cramps. However, the bleeding and cramps aren’t as bad as I usually get on a usual period. Any help would be amazing as I have my first Dr appointment Tuesday so can’t really do much at the moment.
