Help me answer this question and ease my mind

Hi ladies. I had a miscarriage in December. Finally pregnant again, 6wk2dy. Anyway, I'm very scared and wanted to put my mind at ease. I have other children but not recent enough of remembering this answer. When do you start with the morning sickness?  I know odd, but I'm dying for it just so I know baby is ok. I go for a sonogram the 8th but that feels like an eternity. Any help will be greatly appreciated. Thanks ladies ❤️
