Hi Bluesky - totally understand your worry, I suffer from emetophobia which used to completely control my life, but I've managed to get it under control over the last few years.
For me it started midway through week 5, and has gotten progressively worse. But when I focus on it, I begin to feel nervous which certainly upsets my stomach more. So I'm trying to stay calm (easier said than done when you're terrified of being sick!) and make sure I carry some oatcakes with me and water with a bit of ginger in it. Oh, and a plastic bag 😳
So far, I've found that on the days I feel worst, constant nibbling seems to help. I felt particularly sick last night, but I put some fresh ginger in hot water and whether it's a placebo or not, my nausea did subside.
Fingers crossed it passes you by!! x
