Chance of pregnancy?

I am trying to conceive and My period was 2 weeks late for the month of April. It didn't come until May 2nd and it only lasted 4 days. It is now June 23rd and I have not had a period yet. My flow chart says my period should have started 24 days ago and it never showed. I do not have any symptoms of pregnancy so I don't want to get my hopes up and take a test and get my heart broken (I have a 3 year old so I know how this works lol) any advice?
