Anak, if you're worried about pregnancy, it's best to see your doctor or go to a clinic today if you can, hindi na kailangan maghintay pa bukas, para may peace of mind ka agad at ma-address ninyo ang delayed period properly. A PT can help, but a doctor can tell you more about what's really going on, lalo na kung may other symptoms ka. Kaya mo yan, and it's better to get checked soon rather than worry alone.
