Duphaston for not yet pregnant (?)

Hi mommies! Ask ko lang po kung may same situation ba saken na pinagtake na ni Doc ng duphaston kahit hindi pa alam kung buntis? Late ovulation kasi ako then pinagtake ako ni Doc ng duphaston for 14 days 2x a day. My period will fall on the 5th of Feb but I’m hoping na di na ko datnan at maging positive na 😞🙏🏻
