Would it feel similar to constipation?! Pretty sure I felt them like six times in one day! (Yesterday) none since
Your tummy gets hard and a little warm. You will feel a tightening of your uterus that may last 30-60 secs. I have been noticing them around 16 weeks.
For me my stomach gets really hard. Its almost hard to breath and I get a hot flash. Its not painful but can make me stop what your doing occasionally.
