Ay, super exciting na talaga! Honestly, a faint line is still a line, mama, especially if you can see it within the testing window, that's usually a good sign na may hCG na sa system mo. A lot of my mum friends got faint positives around 11 DPO din and it turned out to be the real deal, so fingers crossed for you! Best bet talaga is to retest in a few days with morning urine para mas clear ang result, or ask your doc to do a blood test kung gusto mo ng confirmation na sure. Praying it's positive news for you!
