Is this normal?

One month I think I know my body and the next I don’t. My partner and I have been trying to actively conceive for about 6 months now and before then it was just hope for the best. Last month I got super stressed out about OPKs and tests so we decided this past cycle I wouldn’t chart, test, or do anything.

Now wouldn’t you believe that I’m late for my period and am experiencing absolutely no symptoms at all except for a little dull cramping earlier today. So my hopes are up, yet every test I’ve taken every morning and night have all been negative. According to my apps I’m around 6 days late for my period. Is this normal for anyone else? I’m going insane!!!
