Hi ladies, I'm 5w5d. On Tuesday I started bleeding bright red, went in for an ultrasound and the baby is measuring right where it should be. they saw the sac and the yolk sac. But I have a SCH which was causing my bleeding. After Tuesday I haven't bled at all. Anyone else have a SCH I've read that they occur in 30% of pregnancies.
