Blood clots

Rose-Marie

Hello all :) i'm looking for some advice. I started my period 3 days ago, and am having the worst one ever, the cramps are horrendous, but the thing thats worrying me is that i'm passing clots. Sorry if this is tmi but they are either sat on the pad when i go too the loo or come away when i wipe after using the toliet. Are these clots anything to worry about? My flow this month is exetremely heavy and painful. The only ongoing change for me is that i'm losing weight, i'm not sure if this can affect them? Any advice would be very much appreciated. Thank you in advance :)
