Stretch marks -_-

So I am 38 weeks and made it all the way to 36 with only one tiny new stretch mark. (This is my 2nd child.. I received MANY more with my 1st) but now over the last 2 weeks I have sprouted several more :( I wish I knew why all of a sudden my lotion isn't enough. Guess I just reached my skins max? They really arr not that bad but I am still upset thst they are showing up now.. I was soooo close.
