food allergy I didn't have before??

Sarah
So tonight, I made chicken breast, wild rice and cut up some pineapple for dinner. While my husband and I were eating, my tongue started to hurt and worsened as I ate my meal. I asked my husband if it looked ok and I had to stop eating because each bite got worse! I looked in the mirror and noticed my tongue red with lil red dots (almost blister looking) and noticed that my throat was now starting to hurt. I freaked out and took a Benadryl right away! I have never had a problem with any of those foods. Is it normal to have a reaction/sudden food allergens while pregnant? And will my baby be ok? I'm 25weeks 4 days. Thanks for the help.
