CAR ACCIDENT

So im 37 weeks and my fiance and i just hit a deer im not sure if i should go get checked. we only hit it going about 40 and no major damage and no injuries but now that im relaxing im have some lower back pain and stomach pain. i laid on my left side and she started moving like crazy. do you think i should call l&d; to be monitored or just watch to make sure the cramping doesnt turn into contractions??
