I'm almost 13 weeks pregnant and afraid of getting stretch marks?

I already have stretch marks from when I was younger and put on a LOT of weight incredibly fast but they aren't on my stomach only on my kind of and a little bit on the back of my thighs and have a few on my love handles. They're very faint but you can tell that they're there. I have been using coco er (the cheap stuff not Palmer's or anything) and was wondering if there is anything else I can do to help prevent getting anymore stretch marks or a better type of lotion. I know it's pretty much inevitable that I'm going to get them but is there a way I can soften the blow as to how severe they'll be?
