Hard Time drinking water?

I’m 7 weeks today and trying to get glass of water down is making me more nauseated. It’s weird because I was doing so well with water intake up until now. With no problems I was able to drink more then 8 glasses a day. I have no problem eating and none when drinking juice or ginger ale but for some reason water is just not sitting well with me anymore. I don’t want to just rely on juice and other drinks because they are high in sugar. Even before the pregnancy I never drank anything but water so this is hard for me. Has anyone experienced this or have any suggestions about fluid intake? I eat watermelon daily and other fruits does this help for fluids? I want to try and keep my fluids up because My sac was two weeks behind in size before I had a miscarriage in March and I’m scared and want to make sure it’s growing this time. My first scan is in two days 🙏🏻
