thought maybe someone might have and idea what's going on. My periods are very regular I track ovulation and I start the first day my app predicts but these last two months my period has been awfully Strange with on again off again bleeding to this month today is day for I'm late but I used two tampons and only a spit of blood on both I'm sure it will hit full swing but wth is going on why is my body being weird should I make a doctors appointment I'm young healthy like not any real reason for my periods to be wonky

I've used this app for years so it's pretty spot on at predicting my cycles and with me <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> like it's almost perfect besides these wonky periods
