Clomid cervical mucus before period?


Hi all,

Quick question. I had b2b IUIs on 11/23 and 11/24 and took clomid CD 3-7. I have been extremely dry throughout my entire cycle. I know clomid dries up cervical mucus but for how long. I am just wondering because my period is due on 12/7 and I am getting some AF like cramps on/off and I feel like I am discharging but when I wipe myself it is dry. How long does it make you dry for?
