Hello, it is completely natural to feel protective and anxious right now, but please take a deep breath. You and your wife are doing everything perfectly, and at 36 weeks and 4 days, your baby is practically full-term and very safe.
To answer your main question directly: Yes, there is a natural chance the AFI could reduce slightly, because amniotic fluid naturally begins to decrease at the very end of pregnancy. However, a sudden, dangerous drop is unlikely because your wifeâs blood pressure is normal, her sugars are fine, and her water hasn't broken.
Here is why you should feel reassured right now:
The AFI is Borderline, not severe: An AFI of 7-8 is considered mildly low or borderline. It is not critically low.
Perfect Treatment Plan: The L-arginine sachets increase blood flow to the uterus, and her excellent oral hydration (water, coconut water) is exactly what she needs to do to help replenish and maintain the fluid levels.
Excellent Fetal Movement: The fact that you are counting 20+ movements in 12 hours is the absolute best indicator that your baby is comfortable, getting enough oxygen, and doing well.
Next Steps
What to do for the next 15 days: You do not need to live in fear while waiting for the next scan. Continue your current routine of hydration, medication, and kick counting. You only need to visit the hospital earlier than 15 days if: Movements decrease: If the baby moves significantly less than usual (e.g., fewer than 10 movements in a 2-hour window when the baby is normally active). Fluid leaks: If she experiences a sudden gush or a constant watery trickle from the vagina (this means her water has broken). Real Contractions: If those short Braxton Hicks turn into painful, regular contractions that do not stop.
Health Tips
At nearly 37 weeks, even if the fluid did drop and the baby needed to be delivered a week or two early, your baby is fully developed and ready for the world. Keep up the great supportive work!
