During the rest of the month I use PM pills and cream. During the luteal phase, I use PC and zoft gum because it has weaker phytoestrogens. The reason you use it during the luteal phase is because that's when your body is high in progesterone. During the first half of the month, your body is higher in estrogen so it's better to use estrogenic herbs during that time since you want to replicate the natural hormone fluctuations.
