Hindi ko pa personally na-experience yan, pero a few of my mum friends mentioned similar feeling, parang pressure or heaviness sa chest kapag nag-pump or nagbababy, lalo na pag matagal ang session. Kailangan mo talaga i-check yan with your doctor or OB kasi it could be posture stuff (pag nakatuon lang kami sa feeding, medyo nag-hunch kami), or sometimes it's just engorgement pressing sa chest area, pero better safe than sorry lalo na if it's affecting your breathing. How long ba usually ang sessions mo, at kailangan natin tingnan kung okay lang ang setup mo?
