Query: Not Worth It

I bought three other books at the same time as this one, and this one was one of the worse ones. I did not feel it gave an adequate amount of information on the methods compared to the other books I bought. I don't even think this was a good book as a supplemental to the more in-depth ones. It went to Value Village immediately.The other books I bought were:Taking Charge of Your Fertility (Weschler) - definately the best resource for this; very in-depth and lots of information; definately my go to book;The New No-Pill No-Risk Birth Control - not as good as Taking Charge of Your Fertility, but had good supplemental information and also would be fine as a stand-alone book;Honoring Our Cycles: A Natural Family Planning Workbook - Waste of money! Worst of the four I bought. It seemed as if it was written for a sixth grader who had never learned anything about the reproductive system. Really annoyed me and I didn't even make it through the first couple of pages before tossing it.
