Allergic reaction.

Kayli • I am 28. Married. And have a 6 year old, and 2 year old. Pregnant with my third.
I have never been allergic to bees or anything besides milk. But yesterday I was stung by a bee and my whole hand swelled up and I got a shooting pain up my arm, and when I woke up this morning both of my arms were red and blotchy. Is it possible to get allergies from being pregnant? And if so do they go away when you have the kid? I planned to get a honey bee hive and can't do that if I'll be breaking out.
