Aaah first time mom ka pa lang kaya extra anxious, which is totally normal! Honestly, 39 weeks and 3 days you're still within the normal range, a few of my mum friends went up to 40+ weeks before anything happened, and some even needed induction. The waiting game is the hardest part talaga, pero your body will let you know when it's ready na. I'd suggest you check with your OB kung nag-worry ka, especially if you're seeing any changes like spotting, fluid leakage, or contractions, better safe than sorry, and they can do a check to see if you're progressing na.
