Develop allergies while pregnant?

Anyone else develop an allergy while pregnant? I sometimes have very mild seasonal allergies each year but that’s it. A week ago my husband got me flowers for our anniversary (he’s sweet and well trained 😉 lol). The bouquet has lilies in it and the smell is messing with me! The first couple days my sinuses went nuts and after that I just get fuzzy headed or even nauseous! Never had this happen and I’m wondering if it’s cuz I’m pregnant 😕
