I am sure that we have all heard about the infamous book "TCFYF", I am so happy I got myself a copy, it's beyond informatitive, though it can be a bit repetitive, I am glad I got myself a copy, and I just wanted to recommend the book to you all :) ... Just wanted to share few things I learned....
If your charting for 4 cycles or longer and you are positivie that you are ovulating, she recommends for DH to get a SA ASAP, as charting can help you identity potential fertility problems. She doesn't recommend waiting 1 whole yr (the most 5 months) to see an MD if you are sure that you are ovulating
Eggwhite CM- IS EVERYTHING!!! This is a major indication of ovulation approaching, and though we don't all have it we should have some, even if it's one day, she recommends few things that can increase it.
Last but not least clomid, I got the vibe she's not very for it, because of the side effects, she goes more in depth about this.
All in all, I totally recommend this book :)
