So I use this app and another app to determine when I’m getting my period and I’ve used the other app a lot longer than this one and trust it more. This app says I’m suppose to get my period Friday and the other says Sunday. I just wiped and I saw light pink on the toilet paper. The last couple periods I’ve been getting it days after it says I’m suppose too but never days earlier. Nervous it could be implantation instead of the start of my period.
