Ay, napakabusog ng work mo, nak! Seven weeks postpartum with heavy laundry duty dapat talaga careful ka pa, at that point ang bleeding mo dapat talagang mabigat pa since you're still in lochia phase. Since you're exclusively breastfeeding, kaya mas maaga bumalik ang period mo kasi ang progesterone levels ay tumaas, pero ang hina nito compared sa first born mo ay medyo unusual talaga. Para sa peace of mind mo and para ma-confirm kung regular na ito or may something else going on, better check with your OB para ma-rule out any concerns, one of my mum friends din had spotting issues after her second baby and nag-worry siya, pero after ultrasound lang niya na-ease ang mind niya, kaya go na lang. Hang in there, mommy!
