Severe allergies

Tori
I am currently 3 weeks and 4 days pregnant. I have always had seasonal allergies, but yesterday they started getting really bad. My head is pounding, I'm sneezing constabtly, have a runny nose, and watery eyes (especially in my left eye). Is this happening to anyone else. This is my third pregnancy, and I don't remember this happening when I was pregnant with my boys.
