all of a sudden not thirsty!!

My first symptom was being very thirsty all the time. I would wake up multiple times a night and need a glass of water or I couldn't fall back to sleep. The past two days I've been sleeping through the night and feel barely thirsty. My 10-12 glasses of water a day has decreased to having to force myself to get 8 glasses of fluid daily. Is this normal? 9 weeks and worried it might be a sign of something wrong.
