pains at 33 weeks

I am having a horrible night. I don't want to freak out but I've been in pain for 3 hours now and I don't know what to do. started as bad chest ( hurt to take breath)back pains ,sat in bathroom for an hour hoping I would just get sick and be done, no luck. now I habe been having stomach cramps and having diarrhea issues for last almost 2 hours. idk what to think m is my stomach cramping cuz I may be sick ? are these contractions? it is defiantly painful 😟😟. I don't want to over react my husband has to be up for work in 5 hours and the snow has the roads terrible to get to the hospital from our country home that's 30 miles away? what should I do, or advice to calm pain . thank you
