Ah, stretch marks. I had none with DD, well 2 or 3 faint ones, I lotioned with some sanctuary covent garden mum and baby massage oil (or whatever its called) when I could be bothered, but not daily, sometimes not weekly! BUT, I also did not put on much weight, about 1.5 stone from 8st to 9.5st, I had a tight ball the the front and pretty much nothing elsewhere.
However, i did find for some strange reason that a few more stretch marks appeared when I was breastfeeding . I think I ate a lot more, and perhaps put on a little weight, then it went again quickly with the bf and thus stretchmarks. They are hardly noticeable, faint and clear.
I feel it is likely to be different this time, as I am getting bigger more quickly so my skin is going to be stretching more (i have no idea what I weigh, what I weighed before falling pg, or now). I would love to not have them, of course, but its one of the things that happen to pg women and I am just going to see it in the same way as my grey hair, slow appearing wrinkles, not quite so tight ass, its me.
