Hay, 8 weeks delayed is definitely something you should check with your OB about, mamsh, could be stress, weight changes, hormonal imbalance, or marami pang iba, pero better safe than sorry talaga. A few of us moms had delayed periods din before, and iba-iba ang reasons, so kailangan talaga ng proper check-up para ma-rule out pregnancy or any underlying concern. Don't worry too much in the meantime, but make that appointment soon, okay? Let me know how it goes!
