Sad moment!! 😢

So I made it through my first pregnancy without having any stretch marks and with him I put on 62lbs and he was 9lbs 3oz and I'm 5'2 and a very small frame so I was beyond excited when I didn't get one.. But now pregnant with my second little boy and I've only put on 12lbs but this morning as I'm putting my oil on my tummy I noticed a blue reddish line starting on my tummy!! I was so excited that I almost made it to the finish line with this one without one stretch Mark, but it looks like I lost the war with this one.. 😢😢
