Hallow Dear,

Unwanted 72 is an emergency contraceptive pill which contains high dosages of the hormones Oestrogen and Progesterone. These hormones should come low within a specified range to start the menses. After Unwanted 72, the levels go higher than normal levels and hence it is likely that the periodicity of the menses may be disturbed.

Meprate also is high dose Progesterone. If you have started Meprate immediately after the delay in the periods, you have raised the levels of Progesterone again which will further delay the menses. To have withdrawal bleeding it is advised that Tab. Meprate are taken for 5 days and then after about 4-7 days, the withdrawal bleeding appears. So please take Meprate for 5 days and wait for 7 days later.

I hope this clarifies the doubts in your mind.
