Occasional Breathlessness?

Hi ladies 
Anyone experiencing some breathlessness? I am getting out of breath on an off. I think it's due to my hormones surging, but it can be alarming. 😁
 I also read the below, which is somewhat comforting, as I'm 5w2d. Just thought I would post and see if anyone else can relate? 😄
Thanks guys! 
Early pregnancy. In the first few weeks of pregnancy, a normal increase in the hormone progesterone causes you to breathe more often. This can look and feel like shortness of breath. This hormone expands your lung capacity, allowing your blood to carry large quantities of oxygen to your baby.
