Help Appreciated 💜

Okay ladies, my husband and I are TTC, we've been trying for a little over 5 years now. We've been trying the old fashioned way, legs up in the air and so fourth. My question to y'all is what do I need to keep track of everything? Like idk any thing of what y'all are talking about. Like the tests and all that?! ANY & ALL help would be appreciated, because I'm not exactly sure what I need to do. And where can I get these items!! And congratulations to those with a baby on the way💜
