I am a female 26, weight 59kg, height 1.72m. For over a month now, I feel nauseous after eating and always have a serious stomach pain when I wake up each day. yesterday, I had a serious tommy pain after eating a meal with pepper. Recently, I use the toilet often and my last period wasn t like the former in flow but still lasted 5days. I have been under a lot of accademic pressure for a month too. Also noticed a sign of fever on my mouth.
