i have just come on, two days late, i am normally regular, i was due on the 28th and i when i discovered i was on, i gushed out blood (i know, sorry to be so brutal) and im on unusually heavy, im normally on really light at the start of my period, ive had EXTREMELY painful cramping. nearly brought me to tears and not being able to move, i also have black sticky blood clots come out whenever i pee, and i see them on my pads. i have been trying to convieve for a child, and initially thought i was pregnant, as i have had some symptoms, weight gain and sore boobs ect, i know these are signs of PMS, but im curious, could i be having a miscarraige ???
