Is hardening of the upper stomach a sign of pregnancy?

Answer 1

If this is your only symptom than it is not likely. It could just be gas, bloating or increased muscle mass. Your symptoms of pregnancy will usually appear anywhere from the first week of your expected period to 1-2 weeks after your first week of expected period. Your first signs of pregnancy most commonly include missed period, tender/swollen breasts, change in color of the breasts, fatigue, nausea/vomiting, increased sense of smell, and weight gain.

Answer 2

Could be gas, but get a home test to make sure it isn't just that.
