yes all the time

Yes and it sucks sooooo bad 😩 you will get used to it and just try to take deep breaths and don't freak yourself out!

In your second trimester, pregnancy hormones (the usual suspect) stimulate your brain to increase the frequency and depth of your breaths, allowing you to take in more oxygen for your growing baby-to-be. Those hormones also swell the capillaries in your respiratory tract and relax the muscles of the lungs and bronchial tubes, making you feel like you're sucking wind after nothing more strenuous than a trip to the fridge. In the third trimester around week 31, your expanding uterus and baby have compressed your lungs, limiting their ability to fully expand when you take a breath and causing you to feel like you've just run a marathon when you've only climbed a flight of stairs.

I'm only 20 weeks and starting to have that!!

yup it's normal
