Aww sis, I totally get the anxiety, ganyan din ako dati! Light spotting at delayed period can mean a few things, kaya kahit negative ang PT, meron pa ring chance kung late ka talaga or kung hindi pa enough ang hCG to detect; pero honestly, mas safe na mag-follow up with your doctor para sure na kaya nila i-check through blood test or another PT in a few days, dahil sometimes ang timing talaga ng test ang issue, hindi pregnancy absence, you know? A few of us mums nagtesting ulit after a few days and nakita na namin ang positive, so huwag mag-lose hope yet, pero definitely get checked para may peace of mind ka na din. Fingers crossed for you!
