Membrane sweep or bloody show

My obgyn checked my cervix today and said I am only 1cm (I wasn't dialated at all 10 days ago). The last check did not hurt at all but today it hurt andecent amount and when I went to change I was bleeding bright red. I didn't bleed last time and so I had my husband grab the dr who said it was normal . It was much more than spotting. I could have filled a light pad. When I got home about two hours later the blood turned to brown. I started looking it up but I do not know if that was a membrane sweep or if I am having a bloody show.
