Hello, my name Is emily okeefe. The past 6 days I have been feeling nausea in my stomach, off and on. It gets really cramped up, to the point where I want to get sick. I'm a 16 year old junior, and it's the end of the school year, and I can't offord to miss anymore school. I feel fine in the morning when I go to school, but about a period or two in, I start to feel sick, and have my parents come sign me out. My parents thought it was a stomach bug at first, but are now concerned because of how long it has been going on for. Please help me!
