4 weeks 5 days today - started bleeding yesterday:(

Fabiana
Two months ago I had a miscarriage. After one normal period I got pregnant again. I'm starting my 5th week... but yesterday I started bleeding like if I had my period. I took 7 pregnancy tests... so I  pregnant for suru. I had all the symptoms until like 5 days ago when all the symptoms disappeared. When I felt different I took another pregnancy test and it was positive again. Today I'm still bleeding... can't wait to see my doctor tomorrow to know if everything is ok. 
Has anyone experienced or is experiencing something similar? I'm scared I'm losing the baby again :-(
