Stretch marks...

Jen • Due July 2018 with baby 2
I'm 31 weeks tomorrow and have noticed stretch marks appearing over the last couple of weeks. I appreciate I'm highly emotional at this point in time too, so struggling to determine exactly if the way I am feeling is due to my hormones making me super sensitive!! I understand they're completely trivial, and if this the only negative thing I have to take away from my pregnancy then I am lucky, but I just wanted to know how those of you who have gotten them (or had from previous pregnancies) have dealt with the idea that that part of your body will never be the same? I feel so so shallow and terrible for feeling so upset about them, especially when my husband doesn't care at all, and keeps reminding me that I'm doing the most important job in the world. Will the feeling pass with time or is this something that's likely to upset me until they're faded??
