Pregnancy Sticking to plan and ignoring cravings

Hello! Has anyone got any tips?

I'm currently at target having lost 6st last year and am now 14 weeks pregnant.

I was determined that any weight I gained during pregnancy would be baby and I would continue to follow the plan as I have done for the last 18 months. However this baby wants ready salted crisps and pizza! Well, anything salty and starchy really.

So, any tips on getting through pregnancy and ignoring unhelpful cravings??
