AF is almost four days late now and I have had several Negatives. I even went to the doc because I previously had an ectopic. They did a blood test and that was negative. I'm also having a similar pain on my right side as I did when I had the previous ectopic. Doc said they are very sure it isn't an ectopic. So I have no idea why AF is late and why I have this pain. It's hard not to slightly worry. Has anyone experienced this?
