Feeling blahhh

I just don't feel like anything today. All the food smells are making me gag. I try and eat or feed my toddler and I just gag. I made her a soup and I almost threw up ontop of it. I'm 15 weeks. My nausea was gone since 10 weeks and its bow horrible today.It's so bad and constant my toddler has picked up my gaging noice and does it.
