Allergy Sufferers

I am literally allergic to everything to begin with but when I’m pregnant it worsens 1000x. I’m taking Benadryl around the clock with no relief. Now I have a sore throat, and my ears are even itchy. My head is completely stopped up and I can’t hear anything. I’m only 5 weeks, I’m going to get allergy tested on Monday to start homeopathic allergy shots. But in the meantime does anyone else have this problem and what can I do to get some relief until?? I’ve been slowly dying since 3 weeks pregnant. Help 🤧😰
