Uy, a 2-month delay with negative tests is something you really need to check with a doctor, ha, kahit negative ang PT, maraming reasons why periods can be delayed, at kailangan mo ng professional to figure out what's going on. A few of us moms have had irregular cycles din, pero laging napunta kami sa OB para malaman talaga ang dahilan, whether it's stress, hormonal changes, or something else. Hindi dapat mag-assume based on PT lang, kaya please get an appointment soon, your OB can do proper exams and tests to see what's happening. Huwag mag-alala, madalas lang ito, pero kailangan talaga ng check-up. Take care, mommy!
