First month ttc

Hey there! This month my partner and I decided we were going to stop using birth control and begin the journey to conceive. I have been using ovulation strips but so far no positives yet (due to ovulate on the 12th). While I realize this will only be our first month trying, I'm starting to get scared that this could be a long and difficult journey (d/t family history). Was hoping for advise on a) how to use ovulation strips correctly b) when to start doing pregnancy test strips (do you wait until you miss a period or start testing a certain number of days after ovulation) and c) how to keep the anxiety at bay.

Any advise or suggestions would be so appreciated!
