Heavy Bleeding

Erica
I started bleeding extremely heavy Sunday night ... I'm bleeding and clotting heavily to where I'm going through a super pad a super plus tampons within 30/mins to 45mins. My job consist of standing and hard labor to where I can't go to the bathroom as aften. I can't see my gynecologist til Thursday... please help me .. and tampons bigger than supper plus ? Pads ? Something I can do at home to reduce bleeding.
