Late but nervous to get hopes up too soon

I've been tracking my cycle for about 2 years. My average is about 28 days but that can vary by about 2 days either way. Anyway.... according to both glow and period diary I am 5 days late. I am nervous to get my hopes up because after 2 years of trying its hard every month when AF shows up (especially in those months that were just a few days off from normal). I've been having some really light cramping off and on but not like usual AF cramping, which is stronger. No other symptoms. I want to tell people so that I can have some support but dont want to get anyone else's hopes up either in case it's not so I thought I'd try here. Thanks
