Mini labors and growing bump?

Kay

The last 2 weeks I've had one night in the week in particular where my lower back will hurt more than usual, my hips will hurt (like round ligament but different), last night I felt like I had to poop but didn't, I'll throw up my dinner, then I have an extremely restless night sleep often accompanied by crazy vivid dreams and in the morning my bump is significantly larger, like 25-30% larger... has anyone else experienced this?
