Ay alam ko yan, super confusing talaga pag ganyan after birth! A few of us moms experienced that irregular period phase, sometimes every month, tapos biglang mag-skip for 1-2 months, it's actually pretty normal especially if breastfeeding ka pa or hormones pa lang nag-aayos. Since negative ang PT mo, I'd still suggest checking with your OB-GYN just to be sure lahat's okay, kasi sometimes stress, diet changes, or even thyroid stuff can mess with your cycle post-baby, better safe than sorry talaga, and at least magkakaroon ka ng peace of mind!
