I was not offered a scan and told to go home and wait for the baby to pass through. Thank you in advance.x posted 04/07/2013 by a BabyCenter Member Was this answer helpful? I spotted for a couple of days and then I started passing big clumps of tissue and blood clots. The heavy bleeding with blood clots passing lasted for about 3 days and it was intermittent. I would recommend carrying around the thicker pads with you while you're out and about that way you're prepared when it happens. My doctor gave me a script for pills to insert to trigger my body into a miscarriage but I didn't need to use them. The cramping started after 2 days of slight dark brown spotting. Now 3 days out I feel pretty normal and very slight spotting.
