I took the first test one when AF was one day late. I took the second one today at 5 days late. Both have a faint BFP. I also did a blood test a my 2 days late that was negative. Since one almost a week late could the blood test have been too early to pick up hcg? All I know is that I got another BFP after the blood test and still no AF. AF is also never late. I start on the same am day every month.
