Food aversions...

Kate
So, I'm about 6 1/2 weeks along and haven't had any cravings or aversions to any food. Just had lunch with my in laws and started sweating and stomach was cramping pretty bad as I was eating my salad. (Salad also had feta cheese... Which I didn't know it had in it... Yikes) Is that a food aversion or just coincidental? Thanks in advance!
