This drug is not suppose to be prescribed for u to go buy them urself, a good gynaecologist will give it to u and monitor u strictly while u take them for just five days and u most visit the gynae exactly on the 5th day for further instructions, but since u got it urself I guess u show them to the Dr CU's one can not tell the fake from the pack shown here but from the reaction on ur body, remember it has to do with ur hormones
