could I still be pregnant?

Melissa
a week and a half ago (I was 4 weeks) and I started bleeding heavily and cramping like if I had my period and all my symptoms went away.. my breast arent sore anymore 
But idk.. I feel pressure in my lower abdomen and I'm tired more than usual.. it's strange but has anyone ever gone through what they thought was a mc and ended up not being one?  I know I should go see a de.. I haven't gone since the "mc" because I bought it  would be pointless
