Period Regulation postD&C
My doctor prescribed taking Duoluton L pills for 21 days after 5 days of my wife's D&C (for period regulation and contraception). The pill tries to regulate periods to the normal 28 days cycle. But her normal period cycle is of 21 days. So. should she still be taking pills for 21 days or can she stop it a few days earlier in order to match her 21 days cycle?
