I'm 16 weeks and thought I felt a bruise on my bump today. When I checked there's nothing visible to see but now I've pressed it feels bruised in a line all the way around the bump? Just below my belly button. I've had a look online but everyone else's stories are all when they're near their due date and baby's been kicking hard and things. Just wondered if anyone else has had it this early and is it just my bump growing?
