Well my period was due 5 days ago and it hasn't came. My stomach is just bloated and feels so uncomforting. Every time when my period is coming, my stomach gets a little bloated and then it comes on, but this time it just is bloated. I don't even have cramps just bloating. I feel embarrassed when I wear tight shirts or after I eat because I look a little pregnant. I don't know maybe its stress because I have been going through a lot lately. I'm so confused and this bloating needs to stop plus when I sleep, I try not to sleep on my stomach. What could be the problem?
