Hi ladies!

I'm not sure when to test. My last period was June 15 through June 21, my partner and I had sex June 30th, July 1st, July 4th, July 8th, and July 9th. When would be a good time to start testing? My period is due tomorrow, according to Glow, but I've not had much of any PMS symptoms. I've been a little crampy, moody, more emotional, and my boobs are killing me. Normally before my period, I've got extreme cramps, back pain, and I'm in a good mood. I feel a little off, tbh. Any help would be amazing! Thank you!
