How many is "normal"

I've been having Braxton hicks contractions allll day, and it's weird. I didn't do much, cooked, showered, & basically been laying around all day but I wanna say I've had 20/25 today. This started around 2 pm. No pattern. When it first started I had about 7 & then maybe an hour went by of none, and then some more. & so on. I always drink a lot of water, everyday. I tried changing my positions & stuff that helped but they still kept happening after. I haven't had any in the last hour up until now. But they're not painful just uncomfortable & not consitsant so I'm wondering what this means? Is this okay? This is really one of the first times I've experienced them & they came on so sudden I didn't know this many happened a day. I'm 35 weeks.
