When can I take a test??

Hi girls, I need some help here πŸ˜‚

This is my July and August calendar:

So, my question is; when can I take the test if I can’t wait till 19th? πŸ˜„πŸ˜„

Today I’m on my 23 cycle day. I bought a very sensitive pregnancy test.

This month (or ovulation πŸ˜†) I was doing ovulation test but they were all negative. Maybe I just missed the right time. I had ovulation symptoms a few days earlier as shown in the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> (1. -3. Aug or even earlier) - at that time the other line on the test was also darker.

I fell bloated for some days now and tired, my back is hurting ... I dont know, maybe it’s just my imagination but I need your opinion soo HELP! πŸ˜‚πŸ˜‚
