No linea nigra - have the scientist missed a way to predict the sex of your baby?

[nics1stbaby]

I am currently 30 weeks pregnant with my first baby. Following my 23 week scan, I know I am having a little boy. Two of my very good friends have recently had baby girls. They both had (have) a linea nigra, and I don't. Out of interest, I have asked around and I now know 3 other cases where with boys the Mums did not develop a linea nigra, and 2 other cases where the Mums had linea nigras with girls.

My friends and I realise that something like this is unlikely to have been missed by all those doctors and scientists, but hey, out of fun.. can anyone back this theory up??

[Tinker]

Er, I had a girl and no linea negra! Sorry.

[Tinker]

nigra even!

[Enid]

I had a linea nigra and a girl first time - second time round I don't have one so we'll see!

[WideWebWitch]

I didn't either and had a boy, which supports your theory!

[Snugs]

Sorry to disappoint but I had a linea nigra, which eventually faded away completely, with first ds. Then with 2nd ds got it again, but this time it hasn't gone (or even faded much!)

[dejags]

I had a boy and a linea nigra, so did my best friend

[SueDonim]

I've got two boys and two girls and had linea nigra with each of them.

[Harrysmum]

Can I ask what a linea nigra is?

[ScummyMummy]

It's that darkish line down the middle of your belly that some women get in pregnancy, Harrysmum.
I had one and had 2 boys. I love this theory though Nics1stbaby!

Linea Nigra is the dark line that often runs from your belly button downwards when you are pregnant. It only happened with my first pregnancy, and i had a girl, but the other three that followed (1 girl 2 boys) it failed to appear.

I had 2 boys, nothing 1st time, very pale 2nd

[nics1stbaby]

...interesting hey. Maybe it was just a mad coincidence... then again, perhaps it occurs more frequently when having girls, with exceptions to the rule.

Let's see how the results pan out!

..I just love Mumsnet!

[bossykate]

sorry nic1stbaby, i had a linea negra and have a little boy!

[nics1stbaby]

Ho Hum. It was fun whilst it lasted...

[Ellaroo]

nics1stbaby, my friends & I all follow the same pattern you noticed. Very weird, although mine still hasn't gone so I expect if I have a boy next time it will still be there. Apparently if you have very bad heartburn while pregnant it means the baby has a lot of hair - this was true for me.

[Philippat]

no linea nigras, girl
no heartburn (loads of vomiting though ), lots of hair
Wedding ring on a string (and MIL) said girl, everyone else including MW (not the ones at the actual delivery obviously) said boy

[Tissy]

Linea nigra, girl

Dreadful heartburn, bald

[Joe1]

No line, boy. Loads of heartburn, he too had little hair, not quite bald.

This time no line, but feel it could be a girl.

[Rhubarb]

No morning sickness, no linea nigra, baby resting in classic 'boy position', but still had a girl.

[nics1stbaby]

Ellaroo...

Apparently the linea nigra can remain for at least a year!

oh, a friend of mine had a little girl last week with a full head of thick dark hair, and she didn't have heartburn at all...

I do have heartburn though.. so come 8 to 12 weeks time we shall see hey.. ;o

[batey]

No linea nigra-2 girls. Remember going for a hospital check up in the winter, Consultant had a student with him and asked him what the line on my tummy was called, He got it right, didn't have heart to tell him it was the indent of the seam on my tights!!!!

[SueDonim]

ROFL, Batey!!! What a brilliant story!

With my last pg, the linea nigra sort of peeled off after some months, a bit like sunburn. Weird.

[Joe1]

Brilliant batey

[jemw]

lol batey!

[ionesmum]

I had no morning sickness, no linea nigra, carried all at the front and had a girl. I did get loads of heartburn and dd has a thick thatch of dark hair.
