So many horrible symptoms today. 34 weeks

My body is not happy today. Both my calves are achy, my stomach is constantly tight, I've tried walking, and sitting, and laying and nothing is comfortable. Now I'm having diarrhea.  This is my second baby, so I know I'm not having full blown contractions, but these Braxton hicks are killing me today. I can't seem to get hydrated, and when I do drink water, my stomach seems to get real full and tight. I hate peeing every 5 seconds 😡
