don't want to get my hopes up

okay so a few weeks a go I had thrown up once one night then again the same time the next night...well Friday night I had started throwing up at 11 and until 9 the next morning every two hours...its not normal at all for me to get sick...ive also lost 15lbs In a week but eat just fine besides the days I threw up...my AF isn't due til the 30th and I want to test but I don't want to either because I don't want my hopes up again...what do
