Ay mama, kahit may spotting pa at breastfeeding ka, possible pa rin talaga na mabuntis kahit withdrawal lang, maraming cases ko na narinig from my mum friends na nangyari yan, so hindi sya 100% safe talaga. Best talaga magpa-checkup ka ng doctor para ma-clarify kung saan ka exactly sa lochia stage at para makapagsimula na kayo ng proper contraception na safe sa breastfeeding, like pills o IUD, mas peace of mind kayo pareho, especially since hindi pa kayo ready for another baby agad. Wag mag-stress muna pero do go to your OB, okay?
