Oh dear, I really feel for you carrying all this worry while also chasing a toddler around at 10 weeks pregnant. Please do not wait on this one, go see your doctor or head to A&E today, because a protrusion that feels squishy and shifts when you exert yourself during pregnancy really needs a proper check by a doctor right away, not something to hold off on even if your bowel patterns feel fine. You and your baby's safety come first, and your OB or the A&E team will be able to give you a proper assessment.
