I had the same concern and the pains were so sharp I was sure that something was wrong. Mine was lower abdominal and usually on the right side.
My doctor assured me that it was just a ligament and that it happens all the time.
The suggestion she gave me, get up more slowly.
Or cramping from the spicy food. Did you need to use the bathroom after these pains? If its still bothering you ..you can always ask your doctor what they think for re assurance:)
COuld just be ligaments/muscle stretching to accomodate the growing baby!
