Water intake

Hi mommies/soon to be mommies! Ask ko lang how many liters ang ideal water intake ng isang preggy? I am currently 19 weeks preggy, nagpa urine test kasi ako at sabi ng OB ko mag water therapy ako, eh sa isang araw halos 3 Liters naiinom ko. 😅 Need your advices mga mommies! Thank you in advance! #ftm #godblessmommies
