Nausea and food aversion 11 dpo?

I've been sick to my stomach on & off every day since 4 dpo. I'm also craving either sickeningly sweet food or spicy food, but I feel nauseas right after eating. I never get nauseas (vomit free since 2010!) So this is really weird. I don't have a fever and my breasts feel heavier, but not sore like my first pregnancy. Something definitely feels off, but I don't want to get my hopes up. I plan on testing in about 2 days (AF's due on the 5th) but this is driving me nuts! What do you guys think?
