I have a question so my periods used to be pretty often and I had never missed a period until I had my son after I had him they started back extremely regularly I started keeping track and this app was dead on the date almost every time well in November I was late like 4 or 5 days I figured it may be stress and then in feb. It happened again hoping I was pregnant I wasn’t and now it’s happening again but this time longer than it’s ever been any idea what’s causing it? I have been 10 times stress before and that hasn’t happened I also suffer from an eating disorder and got extremely thin my period didn’t even stop then I am in recovery for almost a year now so I don’t know what could be causing it
