Stretch Marks 😰😰😰

Aizsya
Currently 23 weeks and I have been getting ugly red stretch marks on my left thigh. Just the left, none on my right or on my stomach(not yet, but hopefully never!). Anyone experienced anything similar? Is it because only my left hip is shifting and not my right? 
And what stretch mark creams do you girls recommend? I'm currently using Bio-Oil and I'm not sure if it's helping...
