Once I started showing, I regularly used something to prevent stretch marks. Around 8 months pregnant, I guess I figured I had missed it and was never going to get stretch marks so I just suddenly stopped using it. Now at 39wks, I've got a few stretch marks on my tummy! 😫 Needless to say I've started using my go to stretch mark product again  to maybe lessen the appearance of the stretch marks the best I can.
