Why is never frozen food tasting very freezer burned to me?

Yes, I am pregnant, almost ten weeks. I have heard of strange food cravings and aversions, or strange tastes can mean a vitamin deficiency. I am taking prenatal vitamins and eating a pretty well balanced diet, and not having any weird cravings. I have eaten two different foods within the last few days, neither of which are refrigerated or frozen foods, and I got a very strong freezer burned taste off and on while eating. So it happened 2-3 days ago, then again last night. I was eating frozen broccoli and a pasta dish, broccoli tasted great and the noodles tastes horribly freezer burned every second or third bite. What's wrong with me?!
