Breast milk dried up?

NoName
I'm 18days postpartum.
My midwife told me that as soon as my milk has dried up I can wear wired bras again. How can you tell your milk had dried up? she said it should take 14 days after my milk has come in.
My boobs aren't uncomfortable and they don't feel heavy and I haven't seen my breasts leaking during the night or during the day. I wear breast pads just to be on the safe side and when I take them out they don't feel heavy or wet. 
Are these signs that my milk has dried up?
