Ay, I understand ang worry mo, mama! But honestly, kahit na negative ang PT, kailangan mo talaga magpa-check sa doctor, hindi lang para sa peace of mind mo, kundi para malaman kung ano talaga ang nangyayari sa body mo. One week delay can mean lots of things, at sila lang ang makakasabi ng tama. A few of us went through similar situations, and what really helped was going straight to the clinic para sa proper check-up and blood test if needed, mas reliable kasi kaysa home test lang. Huwag mag-alala, mama, ang doctors ay nakakakita na nito ng maraming beses, at they'll guide you properly. Praying for you!
