invisble cervix after 'period'

[drk.grphks]

Ok, my story is...my last official period was august 7. I missed 2 months of my period. Than 4 days ago I started to have weird brown/red bleeding. I was like ok, it only turns brown at the end. But anyway, this morning I took out the tampon I put in last night and it was clean. I found it strange. My period usually last from 5-6 days not 3 days only. When I checked my cervix I was expecting it to be hard and low like it always is after my period. But when I checked, I could not find it! It is like gone! So far back that I cannot feel it! Should I take another pregnancy test? I am sorry for the frantic and quick post I am just so WTF!
