70ml is about the amount baby takes at 2weeks? If your pumping session coincides with baby's feeding time, you can pump 5-10mins after feeding. Or get a haakaa pump to collect milk on the other boob while you latch. You can try power pumping too but i think it's not encouraged so soon because it might cause oversupply. For me none of the milk booster worked, not even pills from gynae or raw papaya fish soup which money moms swear by. Lactation consultant advised me to give a half feed of ebm first (or formula) and finish off at the breast. That worked for me, i managed to bf exclusively only by 1.5months.
In the beginning I drink a lot of water and pump every 2/3 hours, I also wake up at night to pump. Over 2-4 weeks, the breastmilk regular and increase. You must also rest enough, eat booster & drink plenty of water. I took the pill from my gynae.
May i know whether did your milk supply increase after taking pill?
