How many ovulated earlier??

I'm reading many post about earlier ovulation in here. what happened?? I had ovulation symptoms right after my period which I didn't believe as I never ovulate this early, so I did no test. According to Glow I was supposed to ovulate on the 18th, I started testing on the 13th until now, I got low as result. Is either I ovulated earlier, or I have not ovulated yet which I regularly do every month.
