Can 2 or 3 shots of alcohol or liquor induce a miscarriage instantly? I was extremely I ll with nausea and I kept throwing up anything I tried to eat and had severe cramps and I passed a small hamburger meat like substance after trying to conceive.. And passed the pieces 4 weeks after my ovulation. There continued to be really dark almost black blood and a little bright red blood and blood clot like things passengers for 3-4 days to follow. I am taking a break from getting pregnant now but could this be a miscarriage or failed cycle?
