Hay, alam ko yan feeling mo, ang antayan ng result clarity is nerve-wracking talaga! Honestly, if the line didn't fully clear or darken in that timeframe, best thing is to retest with a fresh PT or go straight sa doctor para sa blood test, yun ang most reliable way to know for sure, lalo na kung may symptoms ka na. A few of us moms here did repeat tests kasi ang first one namin was ambiguous, at nakita agad ang clarity the second time or sa doctor's exam.
