Mama, alam ko yan ang excitement at impatience haha! A few of us tried the pineapple thing and walking talaga, kaya good na ginagawa mo na yan, ang gabi especially mas effective daw kapag long walks. One of my mum friends swore na squatting exercises and pelvic tilts really helped her, at kahit dancing or light aerobics para ma-engage ang baby properly. Pero honestly, basta consistent ka sa movement at hydrated ka, your body will do its thing when baby is ready! Since you're almost at 39 weeks na, best to check with your OB about what's safe for your specific situation, especially kung may concerns ka sa baby's position, your doctor can give you the greenlight for what's best for you. Kaya mo yan mama, almost there na!
