Stretch marks in weird places?

Kacey • So close to meeting my rainbow baby, Carson ♡

Stretch marks don't bother me in the least, but I'm so confused at WHERE I'm getting them, I laughed about it when I noticed.

So I have some on my hips (not so strange) but I have a TON on my upper thighs, like right under the pelvic area. I was laughing and talking to hubby, I said "what the hell, I'm not growing the baby in my thighs!"
