Trying our luck but HELP

Soo me and my partner have decided to see what happens. But being completely new to it all and seeing a lot of stuff about temperature checks and ovulation can someone help a newbie out? I'm highly confused! I have ordered an ovulation test kit but when do I take them? Every day? Also I'm a month off the pill after being on it for 13yrs still haven't had a period. TAI x
