So as a backup story - I may or may not be pregnant. I was about five days late for my period, but then I ended up getting it but for only about 2/3 days (it is ending now). Tonight, I felt very nauseous nonstop to the point I couldn't lay down to sleep anymore. I tried to throw up but it wasn't working, so I kind of forced myself to. I feel much better now that I did. But my question is, my vomit was white and slimy, and to be honest it looked like film. To give a better idea, it looked like when you put toilet paper in water. It was ribbony and very white. What does this mean and what is it? Thank you.
