With DS I had a fairly marked linea nigra. Am sallow skinned and it was pretty dark and went right from just below my boobs to my belly button and then disappeared down my bump and out of sight. Took blummin ages to fade away too!
As now 26 weeks pregnant with DC2 and was convinced the line had appeared by this stage with DS but it may be my mushy brain playing tricks.. Can anyone remember when yours appeared? And has anybody had one in a pregnancy and then not had it in subsequent pregnancies? This is the kinda stuff I find myself pondering at 2am when struggling with insomnia
