For about a month I have had all these symptoms. I'm not sure what they mean,but I have at least three possible solutions

1) Pregnancy (I have had unprotected sex in the last month but took the morning after pill and am on birth control. However I have not yet gotten my period this month should be due next week. I have also noticed I look a little bigger but the scale says I've lost weight %-) how does that work?)
2) Diabetes Type 1 (family history)
3) Irritable Bowel Syndrome (I have dull stomach aches all day but gets worst after eating)

if you have any comments, i'd greatly appreciate it if you could share.
