HELP: I'm eating too much junk food!

Amanda
I'm 26 weeks and I'm feeling awful as I have been eating like crap. I am generally healthy but can't control moderation lately. Part of the problem is grocery shopping when hungry so I can work on that but any tips on how to get back on track? 
I've been eating too many sweets and junk food. I'd like to balance out my eating habits asap! 😕 appreciate your advice and understanding.
