No judgement

Okay so I found out 3 weeks ago I was pregnant. I have been taking a prenatal vitamin since then. And I have attempted to eat right but it's a total lifestyle change because I didn't before. I'll probably eat out 2-3 times a week. I go most days without eating vegetables and sometimes fruit as well:( I promised this week I will start doing better but could the damage be done? I feel like a terrible mom already...
