I did once before when I wasn't pregnant but early in my pregnancy like 5 weeks I experienced it again .Worse feeling ever.
I just experienced this recently and apparently i stopped breathing long enough for my child started to become very active. I’m assuming because oxygen wasn’t getting to her. It felt like I was awake in this horrible dream and when I realized I couldn’t breathe, I remembered reaching for my husband to alert him.. it was my baby jabs and kicks that got me out. When I finally woke up, my heart rate was up. Very terrifying
