Sense of taste??

My period is 2 days late. I randomly will feel nauseous and I’ve been extremely fatigued (been sleeping in until 11ish and normally up by 7) boobs are a bit tender to touch. The weirdest thing though is EVERYTHING tastes so weird and different to me. I’m a huge fan of salt & vinegar chips and I had some yesterday and I wanted to spit them out I couldn’t stand the taste. My fiancé tried them and said they seemed normal to him. Made tacos the other day and those tasted soo bland to me. Anybody experienced this in pregnancy or around time of period?? Any advice would be great! 😊
