Morning sickness worse at 13 weeks!

Harriet 🇬🇧
From 6-12 weeks I had some nausea and a bit of sickness (mostly down to my vitamins!) and some foods I just didnt fancy but that was it. Now this week I have been sick or at least feeling very sick after every meal and now even in between! Has anyone else had it get worse at 13 weeks? Just dont know what to eat and dont want to live off biscuits as my poor baby will be addicted to sugar soon! 🙈😔
