Oo normal yan, mama! Six days pa lang si baby kaya ang uterus mo ay bumabalik pa lang sa normal size nito, that cramping feeling is actually your womb contracting, lalo na kung breastfeeding ka dahil ang oxytocin ay nag-trigger ng cramps na yan. A few of us moms experienced the same thing, especially around days 5-7, but it usually gets better after a week or two, pero if the pain is getting worse instead of better, or if may fever ka, please check with your OB agad para ma-rule out any infection, okay?
