Congrats sa iyong CS, mama! Honestly, most of us in our circle started going up and down stairs around 2-3 weeks na, pero it really depends sa healing mo, if walang pain or heaviness sa incision, pwede mo subukan nang maingat, pero best talaga mag-check with your OB muna kaya lang. A few of us waited a bit longer just to be safe, and some were doing it earlier without issues, pero every recovery is different talaga. Take it slow lang, and if may tumakas or feeling off, stop agad at mag-message sa doctor mo. You're still very early pa, so don't rush it, mama.
