Ahhh memang boleh jadi macam tu! Your body is still resetting after pregnancy and breastfeeding can definitely delay or skip your period altogether, happened to me too, mine took almost 4-5 months before it came back properly even though I thought it would be like before. Best to just wait another month or two and see, but if you're really worried or it's been more than 3 months with no period, better check with your doctor just to be safe lah, they can confirm everything is settling nicely.
