Ay oo, possible talaga! A few of us sa aming circle experienced delayed positive results, especially if testing too early or diluted urine pa lang, kaya yang 2 weeks delay with negative PTs ay medyo strange na talaga, lalo na with your symptoms na parang pregnancy signs talaga (nipple pain, bloating, cramps). I'd really suggest mag-blood test ka na sa clinic kasi that's more accurate than PT, especially this far along, mas malinaw ang HCG levels doon, at para rin ma-rule out kung may iba pang nangyayari na causing the delay at pain, okay?
