Covid? Pregnancy symptoms?

So, before I freak myself out, I want to know how common some of these things are in pregnancy?

-breathing... I’ve noticed it’s been getting harder to breathe the last few weeks, but I just assumed it’s because baby is getting bigger or the masks we are required to wear at work.

-changes in taste... so it’s been getting progressively worse, but I’ve noticed that I’m slowly losing my sense of taste with some things and other things just taste off. Like I seasoned some ground beef with garlic and onion, more than I would normally put on and I couldn’t taste the seasoning at all. Boyfriend said that I put a lot on... I haven’t noticed a change in smell though.

Are these alone valid reasons to be tested? Or could they possibly be just pregnancy related? Has anyone tested positive for covid while pregnant? What were your symptoms? Lol I’m sorry to be so paranoid!! (30 weeks btw)
