Hi miss-c
When i was pregnant with my son (who is now 4) i actually used a tampon as i thought it was AF it lasted maybe 2 days although it wasnt bleeding more dark spotting but abit heavier than usual spotting had some hemmorages when they did the ultrasound but obvisouly i went on to have a H&H pregnancy. Good luck my luv i know its very scary when things like that happen and your probably going to hear a whole mixture of stories, but stay positive. Maybe get your doc to check your progesteron levels too.
