Will baby be okay if I eat a lot of fast food?

Hey moms. So I’m 20 years old and 30 w I know I’m supposed to eat healthy for baby and I do eat fruits and sometimes cook and whenever I try to have salad and I love milk and everything. However me and my boyfriend have a problem eating out it works for our time and we don’t have our own place so I don’t like cooking just because it’s his moms kitchen. I feel guilty for always eating fast food or pizza etc because I feel like my baby won’t be okay (doctor says everything is perfect and she’s healthy). Are there any other junk food moms out there?
