Freaking out..tmi be warned haha

I really need some reassurance, and nothing i can do till tomorrow. If still persists i will go to my doctor. So tomorrow i am 6 weeks pregnant, anyway, last 3 hours ive had cramping in lower left abdomen just near my c section scar., i thought il have a poo, in which now the pain has gone, but when i wiped my poo looked dark green, and almost black in places, and discharge on my poo almost like ewcm but it came from my bum. Im just now feeling sick to my stomach, i looked online and it said miscarriages and ectopic can cause this. Sorry its tmi just bit freaked out
