Breast pumping early advice

Asra
Is it a bad idea to pump as early as now just a few times maybe one or twice a day to activate my milk ducts ?? I dunno I'm worried because I have t been able to breastfeed my two kids because I've been induced and  Have had a c section ... Milk comes in too late and then doesn't stay long enough even if I pump and feed ... Just not sufficient enough ..
I know I can't take fenugreek until after baby is born but any way I can pump and increase milk supply starting now ?
