Labor coming soon?

So for the past few days I been really nauseous and throwing up. I went swimming on Saturday and then for a few hours after it felt like a slow pee. Yesterday I started having horrible back pain with a boost of energy Now  last night I went to bed at 4am and I slept till 7:30-8pm and I woke up too worse back pain in the lower back and I been having cramps and my BM were soft. Has anyone else had this? I'm 38.2
