What you eat doesn't really affect the baby it would more effect you and how you lose weight after baby is born. With my son I gained 40 pounds and definitely had some baby fat after which was probably all the cheeseburgers lol! This pregnancy I am due in 9 days and gained 20 and was in love with fruit this time around and I'm much smaller!
I ate so bad while I was pregnant. I craved nothing but potatoes and bacon cheeseburgers...ice cream lol.
I took 40 minute walks every night though and through in a salad here and there. My daughter was a healthy 6 pound, 13 oz baby born at 38+3. I took my prenatals everyday.
My bestfriends mom ate nothing but whataburger while she was pregnant with my bestfriend and her twin sister, they both came out very healthy
You will be fine. I never really ate healthy either and I have had 2 healthy baby and another one due in 25 days.
You'll be ok you really need to try and eat healthier but I understand I love fruit and vegetables but all I ever want is cheese biters and ice cream with a side of fried chicken and hotsauce... Lol take your prenatals if you don't eat healthy at least :)
