Can drinking a lot of water give you an upset stomach?

I normally don't drink enough at all, maybe one bottle of water a day, a seltzer, and 2 cups of tea. So two days ago I decided I would try to drink a lot more (Around 60-70 oz a day). I've been doing that and have already noticed a huge difference in my skin (I have bad acne) but my stomach is pretty upset. I keep having to go to the bathroom and when I do it's not normal. I also feel super bloated and my stomach is sticking out to the point where it looks like I'm 5 months pregnant 😂Can drinking more water do this? Because I'm not sick or anything. Should I stop drinking so much or is it okay?
