Out of breath!

(First pregnancy so have no idea) Currently only 5 weeks pregnant with no crazy symptoms other than feeling out of breath ALL the time! Only a few steps and I feel like I’ve been running for 20 minutes, racing heart, occasionally a little dizzy…it’s crazy

Any idea how to help/fix this? Could it be a sign of something like low iron etc?

Extremely tired also which I think is normal this early on, I didn’t expect to feel this way this early also :)
