Not thirsty?

I’m currently 13 weeks and I feel like a horrible mom. With my first baby I was thirsty ALL THE TIME, seriously no breaks. But with this one? I sometimes forget to drink anything and will be like “oh crap it’s 2 pm and I haven’t drank anything today.” I don’t know how to stop this, I feel terrible and I carry a huge water bottle with me 24/7 I’m not dehydrated or anything, but has anyone else had this happen? How did you combat it? I started using a timer on my phone but I’m at a loss.
