It is hard to see the changes. I don't mind the GIANT bump I have, and have been lucky to avoid stretch marks so far (but they do run in my family, and I have a few on my outer thighs from puberty that have faded - but actually, so does my DH from a major growth spurt as a teen, so we match!)
The thing that I really struggle with is my veins...I don't even like to mention it, so posting about it is a bit awkward, but since other people are opening up, I will too
I've had some spider and varicose veins on my upper legs for quite a few years now, and they make me miserable...I won't wear shorts EVER anymore and the same goes for bathing suits in public or short dresses and skirts
I plan to have surgery on them once I'm done having children, but until then, I knew pregnancy would make them worse, and it has (although not quite as bad as I had imagined). I can't stand them, but my husband is the sweetest man in the world, and will kiss my leg right where my worst one is. He tells me that I'm beautiful, legs included. And he very wisely pointed out that these are the veins that support my body and our growing baby, and although I don't like their appearance, they're still doing exactly what they need to be doing.
OP, I know there are guys out there who are superficial and would focus on such unimportant things as a few marks on a woman's body, but as PPs said, there are a lot more good men who honestly don't even notice such trivial things about the women they love, and you'll have that too - don't worry about that
