It is normal to have a normal period during oral dydrogesterone tablets, because dydrogesterone tablets are progestins that help to grow the lining and also delay menstruation. However, some women are not affected by the medication during oral progestogen and will have their periods normally at this time. When the period arrives, the medication should be stopped to allow the period to come normally. If you need to take it orally, take it in the second half of the next cycle to regulate and repair the lining. If you want to continue to delay your period and the bleeding is not particularly heavy, you can continue to take it orally to stop the bleeding. However, it is not recommended to take oral medication if the menstrual flow is increasing during the oral period, as it is not particularly meaningful and therefore needs to be discontinued to avoid factors that may cause disruption of the menstrual cycle.
