any other mommies to be experiencing or experienced shortness of breath at 16 almost 17 weeks?

yes!

I don't ever remember having shortness of breath this early with any of my other pregnancies. I was on the phone with my sister standing up chopping up potatoes and I couldn't even talk I had to go sit down

yes, I was talking on the phone running out of breath. and one day I was just sitting at the table with a friend out of breath lok

yesssssss. ....I can't even sing along to songs anymore without stopping for air. ....

I'm earlier than that but I was experiencing that and it turned out I had an iron deficiency

I'm 17weeks now and yes all the time

Im 19 weeks and it's bad I'm carrying twins to

I'm at 15 almost and have trouble going up the stairs
