I stared my period on Saturday very light almost nothing. Then on Monday my flow became very heavy bad bad cramps and lain in my lower back, and so much flow I go through super tampons every hour at least and its dark and liquidy (drippy sorry tmi) and have clots the size of golf balls. Help please I don't know if it is normal!
