hello doctor, I am 5 months pregnant. I have a question to ask. whenever I drink water even for only a glass, I need to go for urination frequently after every 5-10 min. The quantity of urine is not much but I have to go again and again for atleast 3 times after drinking 1 glass of water. so, that's why I can drink much of water during the day. I cannot drink half glass of water at night because it will ruin my sleep when I have to go for urine pass. I got my urine test as suggested but there is no urinary tract infection found in my report. I don't feel any irritation or pain or itching during urination. I don't understand the reason behind this. please clear my doubt. thanks
