Oo yan normal talaga sa breastfeeding moms, lactational amenorrhea kaya minsan delayed or walang period for months pa! A few of us tried exclusively breastfeeding and ganyan din, parang ang katawan mo nag-pause lang ng cycle because of the hormones. Hindi ka worried, pero just to be safe, best to check with your OB especially kung may unusual discharge or pain, para ma-rule out kung may iba pang reason, better safe than sorry lalo na new mom ka pa lang!
