Has anyone ever had this? Got a scan booked for tonight which was rescheduled from a week ago due to Dr strike. I knew when I took this date my period was due around the same time but had read that it was ok to scan while on period. But my period has shown up this morning and I have such discomfort the thought of being scanned later is nasty. Just looking for reassurance I guess - that and to know if the scanner will actually be able to see stuff through the blood?
