Test or no.

I’m so bad at this, and I’m always too afraid of getting a negative that I don’t want to test. The last few months my cycles have been pretty irregular. I had spotting from March 9th to April 9th (the worst thing ever) and then it turned into a regular period at the end. I was expecting my period the end of May and instead I got 9 days of brown tinged CM. Now two weeks later my boobs are a little sore and heavy, I’m so bloated, exhausted, and I have really really watery CM. I just don’t know if I should spend the money on a test or if I’m just ovulating...
