DH and I just started trying to conceive this month. I was reading information on FAM and was thinking about buying Toni Weschler's book, Taking Charge of your Fertility. I'm 41 and DH is 46. Is this method something we should avoid taking into account our respective ages? Is this book better for younger couples TTC? We don't want to waste any precious time and valuable cycles. Should we just see an RE instead? Any help would be appreciated. Thanks.
