Thoughts? My lower back has been killing these last few days so I thot aunt flow was on its way because yesterday I had a bit of pink when I wiped but as of today nothing, just tiny bit of cloudy discharged  but just now I threw up  a little and it feels horrible in my stomach and it burnt a little. It keeps happening. I'm so bloated it hurts. My period wasn't supposed to be due til Saturday any thoughts?
