when should I test šŸ¤”

I hate waiting for my period, and I like to prepare šŸ˜… af isn't due till may 16/17, I ovulated either the 1st or 2nd.... 3 days ago I had brown spotting and noticed it while having sex.... now my cm is obnoxious and very creamy! When I checked it covered my whole finger šŸ˜³Ā
