Do these lines appear to be getting darker? Even just a little bit? Top one I took 3 days ago, middle 2 days ago and bottom was today. None are from FMU. I also checked my cervix today and it dropped slightly and there was a very small amount of brown blood on my finger afterwards. Also have slight cramps, off and on. I had an early miscarriage at 5 weeks in February, so I'm kind of nervous. Trying to stay positive though.
