So I started my period on August 5, 2013. It only lasted 2 days. I have tracked all my periods since February and they have all been at least 4 or 5 days long. On August 13, 2013 I started feeling weird. I got a massive headache and started feeling nauseous. I came home from work and slept from 11pm-12pm the next day. I have been more sleepy in these last couple days. Also, there are some days where I can't go #2 at all and then there are days where anything I eat gives me diarrhea. I've also had a fever. My fiance and I want a baby but we're not really trying. Could I be pregnant? We've gotten our hopes up so many times before and every test I've taken was negative. I'm kinda scared to tell anyone cuz I feel like I am and I get so excited and then I get let down because the test says negative. So anyone have any suggestions?
