Agghh! is this little red mark how a strech mark begins?!

[Peacenquiet2]

So im 35 weeks with dc3 and never got any strech marks with dc 1/2.
Today ive noticed a bright red dot near my belly button where i had it pierced years ago and its like a blood blister type mark, only small but very obvious.
For those ladies who have got strech marks did they start out like this??
I thought id been so lucky escaping them so far but seems my luck may have ran out :-(

Doesn't sound like a stretch mark to me...usually long. I can feel mine under bump and they go redder if the skin is pulled. Hopefully you'll be lucky for the 3rd time. Not jealous at all

mine started out looking like a little thread vein - then it split, and so did the rest of my belly
