Hi doctor, I am under stress these few days (having to go through some work related course and assignments which are due one after the other). This morning and last night I start having diarrhea (not too severe, and not yet watery) and feeling nausea too. I also feel feverish. Just can't concentrate on completing my assignments now. I didn't get good sleep for almost a week (hard to fall asleep, had dreams, and even jump out of bed on weekends as if it is a weekday). Is there any possibility that these symptoms relate to the stress I had? I am not pregnant, and my period is due in a day or two. Normally I do not have these symptoms before period either. Hope you can give me some suggestions. Thank you.
