6 weeks worries!

Adele • 27. TTC baby #1 for 11 months, born July 2015. TTC baby #2 since march 2016 BFP Aug 2017 MC at 5 weeks BFP Oct 2017 🌈 Rainbow baby due July 2018🌈
I'm 6 weeks and 4 days pregnant and my morning sickness began on exactly 6 weeks! I haven't vomited yet but I just feel nauseas for most of the day unless I eat! I'm so hungry all the time but all I feel like is carbs! I'm also so tired I just can't be bothered getting out for a walk and exercising! I nap every afternoon I'm so tired! Obviously I wouldn't change being pregnant for the world but I'm so nervous about all the carbs I'm eating and the lack of exercise I'm doing I'm just trying to listen to what my body wants but I wish my body wanted fruit and veg and to excersise everyday ? anyone feeling the same way?
