Hi mama! Normal lang yan, marami sa amin nahirapan after giving birth kasi ang hormones mo ay still adjusting, lalo na kung breastfeeding ka pa, so irregular talaga ang period for the first few months. One of my mum friends got her period after two weeks din, tapos another friend namin wala until 6 months kaya super variable lang talaga! But since you're only one week in and you're wondering about it, I'd really suggest checking with your OB just to be sure everything's okay down there, especially to rule out any complications, better safe than sorry lagi, diba mama? Congrats sa bebe, by the way!
