Bleeding during pregnancy

I woke up the other day to cramps and bleeding which I thought was weird because my period ended about two weeks ago. I took a pregnancy test which I expected to be negative. It was positive. I took two more one was a different brand. Positive. I went to have my blood drawn to confirm. (Waiting for results). I took a digital it says “pregnant”. But why am I bleeding so much? It’s like a full period. The thing is my pregnancy tests are getting darker not lighter. Has anyone experienced this?

*please don’t tell me to go to the ER. Thank you.
