I had an early miscarriage (5 weeks) on the 16th of Feb and had these on the 3rd of March do you think they are positives? Trying to work out when AF should be due. Anyone had the same experience. Midwife thinks it was a chemical pregnancy as I didn't bleed a huge amount but did bleed for a week and hardly any cramps and had a negative test almost immediately after the bleeding started. Any help/advice?
