question: I have been spittingup whitechunksthat have black in the middleand it has a puke kind of smell and taste to it but as I have it longer it comes more like before I had it maybe once every week but its everyday or everyother day now and its white with a little bit of a gray/black color in the middle and I have been wondering what it was and I have asthma and I m only a young teen 13-15.
