Help!

Teya • Mommy of 2 Angels, and one on the way 🙏
Since about 11pm tonight, it is now 12:25am, I have had sharp upper abdomen pain hurting in anyway I move. My uterus has gotten hard a few times, Idk if those are contractions though...(ftm). I have swelling in my ankles and feet, but I have been on my feet pretty much all day for the past 3 days. I thought the pain was from dehydration so I've drank about 42 ounces of ice water within the past hour and it still hasn't gone away, it's kind of lightening up right now as I type. Is this something normal, have any of you ladies experienced this before?
