Levonorgesteral 750mcg x 2 tablets 12 hours apart?!

i know you have to take levonorgesteral (morning after pill) within 72 hours!.!. but do BOTH pills have to be taken in 72 hours!? would it be ok if you took one within the 72 hour period and the 12 hour apart next one was say in 76 hours!?

or should i just take both pills at once!? like the levonelle one step!? 1500 mcg in one pill!? thanks (i have different brand, old instructions)Www@Answer-Health@Com
