Is this happening to anyone else????

Hey ladies. 
I missed my period in June. I only spotted for a few days in June. It was very light spotting. So this app told me that I would come on my period July 6th. It never came so I chose the option saying that my period is late. Then it just moved my period back for today, the 10th and it still hasn't come and I'm not showing any signs that it would do I put that my period is late again. Then the app moved my period start date to July 12th now. Im getting so annoyed🙄🙄
