Last night something really scary happened. I was sleeping and all of the sudden I woke up and I couldn't breathe for a few seconds but it seemed like forever. It really freaked out my husband and I. I still feel short of breath. Has this happened to anyone at this point in their pregnancy? I didn't think the baby was that big yet to be causing this. 22 weeks today and I'm a FTM and healthy. Thanks for any insight.
