Retarded question i know - but weeks 12-16, that would be 28 days or 35 days? Because if the nolva treatment ends at the end of week 15 it would be 28 days, but if it ends at the end of week 16 then it would be 35. All the sample cycles ive looked at list 12-16, but i dont know if they mean to the start or end of week 16
