Should i go to the hospital?

*TMI* I am 31 weeks pregnant and for the past couple of days i’ve had really bad stomach cramps and “diarrhea” I put it in quotes because it’s never a lot of anything coming out just super painful gas. I’ve eaten the same foods as my husband and my son and they’re fine. Yesterday I found it really hard to get warm in our house so I’m not sure if i had a fever and chills along with the other symptoms but it was weird to me. My daughter that i’m currently pregnant with hasn’t moved too much since i’ve gotten sick, her movements have been weaker. I did call my doctor and she told me to do a kick count and technically my baby was moving while i was on the phone but since hanging up i haven’t gotten much movement. And if i do it’s not strong like it normally is. I’m not the type to go into the hospital for everything but i want to be safe about it and be sure she’s okay. just need an extra push that’s all.
