Mama, please go to the ER or call your OB right now, at 40 weeks with water discharge and bleeding, you need to be checked immediately, hindi na pwedeng maghintay. This is your baby's safety, at ang doctors lang ang makakasiguro ng what's happening.
Alam ko nakakatakot lalo na first baby, pero better safe than sorry talaga. Let me know how you go, ha? Rooting for you and baby!
