Uy, I feel you, ganyan din ako with my second, negative pa rin after a month delayed kaya super stressed ako! A few of us moms experienced false negatives, lalo na if tested too early or diluted urine, so definitely worth getting a blood test done ASAP kasi mas accurate siya than PT, lalo na kung medyo matagal na ang delay mo. I know you're busy but honestly, sis, kahit quick lang ang checkup at clinic, mas peace of mind mo agad if you know for sure, wishing you the best and fingers crossed for your third baby!
