low amniotic fluid range

Ashley
Hit 38 weeks yesterday & went in for a scheduled ultrasound to see how baby was doing. Everything seemed to be fine but now that my OB has reviewed the findings, she's noting that the amniotic fluid is at a 7.7 - when it should be in the 8s still...
Of course this has me searching online & reading things I probably shouldn't -- but wanted to come on here & see if anyone else had experience with this before???! My pregnancy has been textbook the entire time and this news- ESP so close to the end- is freaking the ish outta me! 😫
Please send good vibes - I just want baby to be okay & safe!
