Understanding Amniotic Fluid Levels and Their Progression during Pregnancy

Question

At 23 weeks and 3 days, my amniotic fluid index (AFI) is 28. Will the AFI level naturally regulate as the pregnancy progresses? I am currently at 27 weeks and will be going for a check-up soon.

Answer 1

Hey mama, I remember being really nervous when my midwife said my AFI was borderline low around 24 weeks. She explained that amniotic fluid fluctuates a lot because baby is swallowing and peeing it out, and even how hydrated you are that day can change the number. I started making sure I drank tons of water and coconut water, rested on my left side and took it easy. By my next scan a few weeks later my AFI had crept back up and stayed stable through the rest of pregnancy.

As long as your doctor is keeping an eye on it and your baby is growing well, a single low-ish measurement at 23 weeks isn’t usually something to panic about. Fluid levels tend to peak in the third trimester and then slowly decrease toward the end. Keeping yourself well hydrated and avoiding too much salt seemed to help me. Your care team will let you know if they need to monitor you more often or if you need to take any special steps, but most of the time it sorts itself out. Try not to stress too much and good luck at your next check‑up!
