Food intolerance???

I’m not sure who else to ask because google has been of no help, but this whole weekend I’ve felt really sick. I made dinner the other night and after taking a few bites I got a horrible migraine that almost made me nauseous. Then today I’ve just felt off and queasy and tonight I’ve just felt sick to my stomach. The only thing I know that I’ve eaten this weekend that I normally don’t is the dill herb added to the salmon I made.

I didn’t get the migraine until after I added it. Would this be a food intolerance thing?

My husband and friend who also had the dinner have had no side effects after eating so I don’t think the salmon was bad. Idk it’s just been a weird weekend for me
