Negative or Faint Ovulation Tests?

June

I've been TTC ever since I had my first miscarriage back in 2018 and have been recently taking ovulation tests to see when I ovulate. From Glow's prediction I'm supposed to be ovulating from the 5th of January until the 11th, my period is irregular. However, I did get my period last month for 6 days but it was very light. How do I know if I'm really ovulating or not? When I check my CM is clear and a little bit watery but I'm still very new to all of this and need a little advice.
