Covid related smell distortion & pregnancy

I had covid at some point last year. Not sure when, as I was tested multiple times and was always negative. Anyways, I started noticing weird smells about 2 months before I got pregnant. Things tasted weird to me as well. I found out that I was pregnant almost immediately, so I know it wasn't a symptom. But after pregnancy, EVERYTHING smells and tastes like sewage except for a few things like avocados, potatoes and other bland foods and also anything sour or citrus. I can't stomach peanut butter or most proteins. Please note that this is NOT a loss of taste or smell but a total distortion. I can still smell the strength of something. Car exhaust fumes, garlic, poop diapers etc all smell the worst but smell the same just stronger or weaker as they normally would. I can't smell if milk or food is rotten and I can't find anything that I can stomach and keep down. I'm already pretty nauseas and gag/dry heave or throw up most of the day so this just makes it worse.

I've tried b6, unisom, preggie pops and sprite and crackers and nothing seems to help. Even saltiness are offensive tasting!

Is there anyone else who's also experiencing this and what do you do? I'm in need of some good nutrients that are not offensive to my taste and smell and ALSO gentle for pregnant women suffering a lot of sickness.
