I didn't feel too good with a spur of the moment decision I grabbed the trash can.

So I got up this morning and I felt fine.  Went to use the bathroom, sat on the toilet and then it hit me. I didn't feel too good with a spur of the moment decision I grabbed the trash can.  Luckily just in time.  I hadn't eaten because I had just woken up.  So here I was on the toilet with a trash can in my hands and all that was coming up was stomach acid.  Worst taste in the world!!!  I finished using the bathroom and once I stood up I felt like a million bucks.  What would do this?  My hubby and I have been trying to have a baby, could I be pregnant?
