Stretch mark Creams?


So my mom has been on me about getting some type of cream to help with stretch marks. And no matter how many times I tell her I'm not worried about them; that this baby is a huge blessing and if it means stretch marks then I'll take them, she keeps on! The other day I was telling her how much the stretching actually hurts and that I feel like my stomach is going to bust(I'm only 18weeks!) and her response was of course the creams.

So ladies, what are you all using?
