I was prescribed Norethindrone. 35mg to delay my period. Online it says take 5mg TID but I was only prescribed. 35mg. Will the lower dosage work? I'm afraid it isn't going to be enough to delay my period.

Discuss with your Dr. Your physician likely had a reason for prescribing the lower dose, based upon your particular situation. That's the problem with generalized information on the internet; it does not and can't take individual situations into account.
