Question!

lala • Blessed with an amazing 1 year old son. Have been ttc#2 for 8 months
I didn't use ovulation strips or tracked my cycle when ttc#1 we just had sex every month and it took us 4 months to conceive. Well now we're trying for #2 and I'm just confused on what these means. I got 2 different ovulation kits one is LH surge and the other is NO LH surge. 
What do they mean?? TIA 🤗
