Uy, I totally get the excitement and the anxiety, lalo na after 20 years! Honestly, you're right na the first morning urine is really the most reliable para sa PT, the hCG levels are more concentrated talaga, so go ahead and test again pag gabi (or first thing in the morning bukas) following the instructions ng kit properly this time. Those symptoms you're describing, the queasiness, increased appetite, and that weird food aversion thing, they do sound pregnancy-related, pero at 41 and with your situation, I'd really encourage you to see your OB soon para ma-confirm hindi lang through PT but through proper testing (blood hCG or ultrasound) so you know for sure at makakuha ng proper prenatal care right away kung positive ka na. One of my mum friends who got pregnant later in life swears na ang doctor visit agad talaga made a huge difference sa peace of mind niya, worth it, especially sa age mo ngayon. Good luck, mama!
