Hi ladies sorry for long post but

I came off my period 24th may on the 30th and 31st of may i took some ovulation tests and there was a very very very faint line. I didnt take any over the weekend as forgot but today i have taken one and there is no line not even a faint one? Does this mean i've probably already ovulated or not yet? Glow predicts the end of this week for ovulation. I'm going to take one for next few days see of anything changes.

Any advice appreciated. Thank you ladies. And good luck to others ttc.
