Mama, kahit normal ang lochia sa first few weeks, ang amoy na parang bulok ay hindi talaga dapat ganyan, mas maganda na i-check mo agad with your OB kasi baka may infection na nangyari, especially after CS. Usually by 6 weeks the discharge should be minimal na at walang strong smell na parang yan, so don't wait lang, get it checked para safe ka at ma-relieve ka ng worry. Ikaw ang nakakaintindi ng body mo best, so trust your instinct dito, ha!
