i recently have been checking my cervical mucus, which is SOOOO easy if you know what to look for. all you have to do is look at your toilet paper when you wipe in the bathroom... when there is mucus you are ovulating. that's pretty much it, although the book explains a lot more about it...
i've been reading a very informative book about it, and it spells everything out clearly. it's called your fertility signals by merryl winstein. it's an easy read, and has been accurate thus far. best of luck, i hope you get your baby soon!
