How to prevent stretch marks??

I'm 21 weeks and have just started to pop I don't have any stretch marks as of yet and would like to keep it that way for as long as I can.

I understand that they are genetic but I also believe that using creams or oils can help prevent or delay them.

I'd rather try something and see if it helps then try nothing, you know.

So does anyone have any suggestions for preventing or delaying stretch marks or decreasing the chances of them ?

Thank you lovelies ! 😊
