Stretch marks!

I'm almost 35 weeks and my belly button piercing caused a stretch mark to form. No big deal. But, I started applying tea tree oil to the stretch mark (I read it helped with stretch marks). I have been applying for 2 days and I have noticed a difference! It really itches now, but they are fading. Maybe it itches due to the skin healing?? But I thought I would share with y'all, just incase someone wanted help preventing or maybe even fading stretch marks (:
