Edit Period

Jocelyn • In a happy relationship with the love of my life.
Me period was expected to start on Tuesday but I've got it today. I don't typically have any problems editing my periods with Glow but it won't let me this time around. I click the button to say I got my period today and it only allows me to edit my last period, not the upcoming one. It tells me I can't edit future dates or add a period so close to another one...
