Finally finished Taking Charge of your Fertility! All 500 pages! Whew😳😩 haha but wow, I feel so educated about fertility now! I thought I knew everything before but definitely NOT. I've learned so much about avoiding pregnancy naturally(after childbirth), how to accurately chart BBT, how to observe CM & your cervix and determine your BIP(basic infertile pattern), ALOT about anovulation and conditions that will prevent regular cycles/infertility, dealing with miscarriages & how to see one on your chart, causes of unusual bleeding during your cycle, PMS, pleasing both you & your partner during sex, tricky cover lines and different charts, and just so much about ovulation, BBT, and your fertility signs! Definitely was worth 20$. I totally recommend this book if anyone was thinking about getting it.
