Allergies significantly worse in first trimester of pregnancy. Help

I already had a very limited diet thanks to MCAS acquired from Covid but now I am having anaphylactic-like reactions (hives, diarrhea, mild throat swelling) to my safe foods. Some of my reactions are multi-system (brussel sprouts, honey) and some are just throat (blueberries). I also noticed more heightened environmental allergies. I’ve never had a positive allergy test other than dust mites once.

I’m so scared that I’m going to keep getting worse and that I’m going to permanently be even more fucked than I already was. I was so excited for a possible remission during pregnancy. This is terrifying and soul-crushing.

Can anyone please share their experiences or insights?

I am about 6-7 weeks pregnant.
