Ay, no judgment here at all, mama! Honestly, the anxiety is so relatable, I was exactly like that too. So here's the thing: exclusive breastfeeding can actually mess with your cycle even after it comes back, lalo na if your baby is still feeding on-demand a lot. Some mums I know had irregular periods for months after their cycle returned, with delays and surprise gaps in between, kaya hindi automatic na pregnant agad if you're late. The negative tests on those dates are pretty reassuring, three negative tests is solid, but hormones from breastfeeding can definitely throw things off, especially if your little one is feeding frequently or going through a growth spurt.
That said, since you're still anxious and want to be sure, it's worth a quick check-in with your OB just to put your mind at ease and maybe discuss what's going on with your cycle, sometimes they have insights based on how frequently baby is feeding. In the meantime, try not to stress too much (easier said than done, I know!); your body's probably just being its chaotic breastfeeding self. You've got this, and you're not alone in this worry!
