Amniotic fluid is low. Advise to admit for hydration

Hi po. Sino po nkaexperience neto? Naadmit po ako for under observation kse mababa yung panubigan ko po. From 9 to 6.7, advisebto hydrate thru dextrose. Last week po kse, nag water therapy ako 3-4L a day para po sa 4D and para mtanggal yung single loose cordcoil ni baby. And then today po yung follow checkup ko. Imbes na madagdagan yung tubig, bumaba po. I dont know whats the cause or reason. And then sa monitoring po, nkita nila may contractions ako, wala nman pong pain and closed cervix pa. Sna po mgiging okay ang lahat. ? Update: Nadischarge na po kmi from hosp, 2days admitted. Thanks God nag increase yung fluid ko to 7.9. And still closed cervix. Bedrest po ako til nexy checkup and continue ang water therapy.
