Sweets triggering my nausea

So since I was 7 weeks I’ve had severe morning sickness however I’m 12 weeks now and for the past two days I’ve felt a little better. Yet I notice if I eat anything like ice cream, yogurt, pie anything like a dessert or sugary , I get sometimes a really bad taste in my mouth and nausea after but mainly nauseous. Yesterday I was okay rarely felt nauseous same with earlier today…until I had a slice of key lime pie and all day I’ve had nausea heartburn the whole 9 yards lol. One day last week I had yogurt then got sick right after. Same with after eating a waffle. Am I the only one like this??
