What can get rid of these??

So I’m almost 29 weeks pregnant and I’m finally starting to get some stretch marks. I thought I was going to get lucky and avoid them at all costs, but Im getting them under my belly and on my sides. Im already super self-conscious and I’m losing all confidence I built up because of them. They’re purple and I’m continually dealing with a rash on top of them. Sadly I’m starting to feel more and more disgusted with myself through this pregnancy. I’ve tried cocoa butter and lotion but neither seem to be working. Someone please help!
