I took a test yesterday to get a 2nd line, but as AF is supposed to arrive today or tomorrow I took another test today only to get a negative (or at best very very faint positive, I can't tell). Has anyone had that happen to them before and did it go onto be positive? Or should I anticipate AF showing up soon? Below is today's test. We have had a chemical miscarriage and a MMC at 10 weeks so trying to remain neutral here.
