Question

I'm 40 weeks and yesterday I puked twice and it left my stomach completely empty. Then I've been experiencing loose poop (sorry tmi) and my lower back has been doing nothing but aching, and also my lower stomach. Then I threw up again during the night and my poo has still stayed the same and it feels like a body ache you get from the flu but only in my back from the waist down. Baby is low, and I've experienced more pressure. I'm not sure if I should go in to the hospital if this is the beginning of labor or if something is wrong? Has anyone ever experienced this or is experiencing this? Thank you!
