Is this normal? 😅😅😅

So I’m currently 25w today... I’m 5,3 and I’ve always been told I have a long torso, but... in the last month I’ve gotten all these stretch marks which I know is normal but in the last 3 days I’ve been in PAIN from my hips down because of how dry my skin is... I use Vaseline which soothe but I reached a point Where I can’t see what’s going on under my belly and only can see with a mirror... I was super irritated today because of the pain and had to see what was going on, so I shaved... when I shaved I found out I have stretch marks leading to my vag....... like an inch away from the boarder, I feel super awkward asking someone close to me, but is that normal?! Stretch marks down there? And why? If it’s normal or can happen...
