Hey mama, I know it's scary when the bleeding seems to stop tapos bumalik ulit, pero totoo yan, especially kapag EBF ka, ang hormones mo ay nagbabago pa rin at sometimes the bleeding does come and go like that, lalo na around week 3-4. A few of my mum friends experienced the same thing and their doctors said it's because breastfeeding stimulates the uterus to contract, which can trigger bleeding again. That said, since you're on week 4 na and the bleeding is still malakas, I'd really suggest checking with your OB just to be sure everything's healing properly, better safe than sorry, lalo na with postpartum stuff. How are you feeling otherwise, any clots, dizziness, or fever?
