Upset stomach all day:(

Hollyanne
Ive had an upset stomah and diarrhea all day and am wondering if it could be causing contractions or if it is normal. I am 35+3. My butt has had enough (tmi) and it is aggravating my hemmoroids. I am having pains in my stomach before i go to the bathroom and during. Sometimes when i walk around but it seems like regular upset stomach pains. Any ideas or think its alright or should i be worried?
