Yes! The same thing happens to me and has been for some time. Im 32 weeks now and never really asked or heard of it happening to anyone else. Its like I can feel it in my chest when im in certain positions....unfortunately I don't have a reason/answer as to why it happens but youre not alone.
My doc said it's likely cuz of baby's position, and to change how you're laying. So I would flip to my other side, or prop myself up more, and even deep breathing worked to slow it down.
Yeah I figured it was something to do with baby's position. I get scared and flip over immediately because I don't want to cut off any blood flow or something to baby.
