When did moms who have been pregnant before get stretch marks? I'm paranoid I will get them worse now that I am on complete bed rest due to a heart condition I have. I have gained weight slowly (lost 20lbs due to HG in first trimester, have gained 5lbs back) and I eat healthy and lotion every day. I know stretch marks are primarily hereditary and there's nothing I can do to completely prevent them. I am 21w5d currently (21w exactly in photo) and have no stretch marks besides the ones I had on my hips before pregnancy. However, I'm curious to see when you guys got them if you got them at all! Sorry the last option is such a huge gap!!
