random wake up and sick

Anyways about 3:30 all I can remember is catching a foul smell, my guess is it was my husbands night breath lol which has never bothered me before or even slightly disturbed my slumber, last night was very different.....I catch a whiff and my stomach churned so I turn to my other side and suddenly in that space between awake and sleep my brain starts throwing all kinds of repulsive smells at me, old cheese/feet/public restrooms, those kinds of things. I was desperately struggling to pull myself to wake mode because I truly thought I was going to retch in the bed. I finally got myself up and in the restroom where I sat for a good 15-20 min...now sometimes if I haven't uhhh "went" for a while my tummy will get a little upset nothing like this but still kinda sour so I made sure I did my business in basic desperate attempt to have that about to lose it all feeling dissipate. Well it didn't, I ended up getting in a cool shower where I laid on the shower floor as the water ran over me sight let dying from nausea until a little past 4:30 when suddenly the queasy feeling started to subside at least enough to dry off and crawl back in bed. 

So I know this is long but my question is has anyone else experienced this and can you tell me if you were or were not pregnant. If you weren't was there a different reason for this crazy tummy game??
