Hindi ka nag-iisa, mama! A few of us CS moms experienced the same thing, parang umuusad na parang ok na, tapos biglang may dark red ulit, it's scary talaga. Since you're only 5 weeks post-op, it could be normal lochia patterns, pero kasi CS wound ka, mas importante na i-check with your OB para sure, especially kung may clots or kung mabigat ang dugo, hindi worth the worry, better safe talaga.
