Had my first ultrasound on Friday at 8 weeks and the doc said I had a 60% chance the pregnancy wouldn't be viable -- she saw the gestational sac but no embryo. Sure enough, Monday evening the bleeding began. Tuesday was terrible -- an unbelievable amount of blood, several large clots, bad cramping. Woke up totally fine today (physically, anyway) and had just light, minor bleeding throughout the day, and almost no cramping. Do you think the worst is over or should I brace myself for more? I have an ultrasound on Monday to make sure there isn't any tissue left...
