Uy, mama, please talk to your OB first before trying anything, labor induction is really something they need to monitor, okay? 39 weeks is close na, but your doctor will know if it's safe for you and baby.
A few of us moms have been there, excited na rin kami to meet baby, but honestly the safest route is always through your doctor. They might recommend what's best for your situation. Stay safe, ha!
