Hi, I just started using the app, and before now I didn't really track my period, so I sort of estimated my last period dates. I know I was on my period on Christmas Day, so I used that week as my dates. I'm also not sure how long my cycle typically is. I wanted to use the app to start tracking things the way I should, but the dates are off right now, it says I'm on my period but I'm not and I don't know how to change it. My period should be happening in the next couple days, just not yet. Does anyone know how I can fix this?
