I am something like 4 weeks pregnant (not sure as cycles are extremely irregualr) A few days ago I started getting a pinkish colour in my discharge, not all the time, and one day I didn't have it. What's worse is I@m out of hte country for a week and have spoken to the midwife but the first date for a scan I can get is Feb 26th. Is this a sure sign I'm losing the pregnancy?
