Ovulation kits??

Hello all! I am new here and looking for some advice. :) My husband and I are ttc for our 2nd. We have just been letting what ever happen, happen for 2-3 months and are considering trying ovulation kits. I just bought the Clearblue Digital tests and was wondering if they are a waste of money or if anyone suggests not using any at all? I’m new at this planning thing 😱 (we had our 1st about 8 years ago unplanned) Any advice is appreciated! 💛
