M.L.
You already have 16 answers, but I thought I would throw my two cents in. I tried hormones early on in my marriage, but had to stop. Like you said, they made me "wacky" (to say the least! I felt like a raging lunatic). I read the book Taking Charge of Your Fertility. I used that method, twice, to successfully get pregnant (and it worked quickly!) I've been using the TCF method for over a year now, with no pregnancies in sight. (Trust me - I've been married 6 years, and have two kids. This feels like an accomplishment! haha)
So. All that said, I like the FCM method. I carefully chart my temp and "fluids". We use condoms on what I call the "danger days" and breathe a huge sigh of relief the day after I ovulate (which I know, because I've been charting). I use FertilityFriend.com to keep track of things. They have an app which makes it 1) easy to find in the morning and 2) super easy to show my doctor when I go in for visits when my "first day of my last period" was.
Sorry for the novel! Msg me if you have more questions...
