I'm 25wks pregnant with my first baby and about 3 weeks ago a trace of a linea nigra started to show. It's not toooo dark, but it can be seen.
The thing is, from bottom to top it's as if it wanted to "avoid" the navel when it gets there haha, it sort of goes "round" it and then goes on straight until the top.
Is this normal? Has anyone out there had the same?
