Stretch Marks!! 😩

Hi all, this is my first post! I am 13w+5 with my first pregnancy at 27. I am very petite, just 4ft 10&3/4" tall and I have been in maternity clothes for 4 weeks. I have literally just noticed stretch marks on the front of my stomach! I have been getting my husband to bio oil my belly every other night for weeks now! Please could someone recommend something else that you have used?
