I'm only 21+5 but my bump is bigger than normal (in most people's opinion ) I've got a pregnancy belly bar in, because i want to keep my piercing and I also don't want two big scars across my tummy if I take it out. However, I've started to get stretch marks coming off it as it's stretched to the max. My mum's bought me some bio oil to use, so I'm going to start, but how effective is it? Is it likely to stop the stretch marks in their tracks? If not, is there anything that will? I'm not vain or anything, but a little worried that the stretch marks are starting so early!!
