Balancing supply

Ti

Hello! I am 4 weeks post partum and have been EBF but will be replacing some sessions with pumping so my husband can join the fun, in prep for me working again in 5 weeks, and so I can provide to another mom. I tend to have oversupply issues and am already on sunflower lecithin. I am wondering about when I pump. I want to be able to help a local mom out but dont want to mess with my precarious balance of no clogs right now. Baby currently nurses on one breast at a time (fast let done and copious supply) and nurses for 5-12min. When I pump should I only do one breast like if nursing? Do both breasts to make sure I help the other mom? Or will doing both boobs for pumping but not nursing mess with my boob non clog balance?
