Idk what to think here..

Update "6/22/17": i had spotting this morning and my app says I should have my AF tomorrow but I know some ladies had light spotting and were pregnant so Im stilm going to wait and see what happens tomorrow and go from there.

Has anyone ever had on time cycles every month then all of a sudden your AF is late for some reason? Ive been on time since January when I went off of birth control and my cycles have been 28 days until this month I am going on cycle day 33 and I dont have any pregnancy symptoms either I even took a Clearblue pregnancy test and it was straight up negetive. I keep putting that my period is late on this app and it says maybe I will start in 2 more days I hope so because I am ready for AF to show up and get it over with. But seriously has anyone ever had this happen to them?

Oh and I should probably mention that my husband and I last ttc on may 29th and that week I took a clearblue ovulation test with the 2 lines and I was pretty sure it was positive I even had my husband look and he could see the two lines and that was on a thursday june 2nd soooo that would be the only chance of pregnancy if this is what is going on with me but like I said I havent had any pregnancy symptoms or implantation cramps or bleeding. So help me out ladies what do you think? Has this happend to anyone?
