Hey mama,
I can understand your concern. I hoped that I wouldn’t have stretch marks too (or at least not too many).
I alternated between almond oil from L’occitane and Palmer’s cocoa butter - the oil for the night because I couldn’t stand that oily feeling and the cream for the day.
No stretchmarks this far :) also, I moisturised quite a bit with Jergens.
You could try this and see if it works for you :)
