How to just "let it happen"

Does anyone else have a hard time just "letting it happen?" My husband and I are beyond excited and ready to have babies, we just got married in Sept. We have sex all the time and I have this app plus taking ovulation tests. It's so hard to NOT try. Especially when my husband wants nothing more to be a daddy (and me a mommy) How do people try but not try?! So frustrating! & I don't get all the lingo used in this app lol
