Need some advice.

Today I threw up after I smelled my coffee and usually that’s my favorite scent! 😫 (I haven’t felt sick since and am able to eat) I’ve been feeling extremely tired, sensitive, having indigestion and my nipples keep changing colors for about a week and a half now. I have one child (which I had awful morning sickness with but no early symptoms). I tested today and it looked neg. but I have never been this sensitive to smells other than my first pregnancy. Any advice?
