I woke up this morning with my tummy looking like this. This happened with my first but I never really inquired too much about the reason for it. With my first it happened around 16 weeks and when I have a full bladder in the morning. So I thought it was my uterus being pushed up. But I am only 10 weeks so I don't know if it could be my uterus. I have more pictures from different angles if it helps.
