Ay, yes! A few of us moms here went through the same thing after ligation, and honestly, it can take a good 6-12 months for your cycle to settle back down, some of my friends' periods stayed a bit irregular even after that, kaya it really varies from person to person. The good news is it usually becomes more predictable over time, pero since you're a few months in pa lang, your body might still be adjusting to the hormonal changes. I'd suggest checking in with your OB about it though, just to make sure everything's normal and walang iba pang concern, better safe than sorry, diba?
