Please help need advice

I know it’s the wrong group but seen so many positive test I just want some advice my flo app says I’m a cycle day 30 which is due today so far nothing all week I’ve had clear stretchey cm which I know means nothing. Glow says I’m due next Tuesday but I’ve never been able to change my cycle days . How long did u wait to test ? I don’t want to get my hopes up as last month I was a 29 day cycle and came on the 30th day which I was devastated about. Please no hard hit comments we all in this together 🙏
