Is it still there? Or was it just once when you wiped? The slimy stuff was prob just cm, if your anything like me, I have terrible gushes of the stuff!! I was spotting on and off for almost two weeks. Mostly brown, but last sat when i wiped once there was bright red mixed with simy stuff.....exactly like you!!! All was fine though, midwife said especially around week 6 and 7, our uterus is stretching and sometimes that causes our cervix ( the bloodvessils ) to engorge and bleed. Dont worry, as long as you are not cramping and it doesnt get heavier, I think you are fine
