Advice on what to use to test ovulation?

Ly

Hi ladies! We are about to start TTC baby #2. I had no issues tracking my cycle for baby #1 because I was so regular, but my cycles have been so irregular since delivering that I think I need to use ovulation strips or something for this time around. I’m doing BBT and CM but figure adding this cant hurt. Any advice on what type or kind to use?? This is all new to me! Appreciate it!
