terrified to test!!

Katie
Holy cannoli! 
So for the past 7days my opk tests have been positive. My body temp isn't high but it isn't low either. (It's like hovering around 98). I usually only ovulate 1day a month and then get negative opk tests. I'm dizzy, nauseous, tired, crampy but I'm so afraid to take a test and get a negative. Any tips?
