Thanks for your query.
The tablets given to you are progesterone tablets
, generally given to induce withdrawal bleeding.
Also, please understand that sometimes it takes upto a week after progesterone withdrawal for bleeding to start.
So, wait till one week is complete after finishing the tablets.
In case you do not get your period, please see your gynecologist again.
Do not worry, as the medicine would not cause any untoward effects on your unborn child.
