Yikes- Choking

Just woke up choking... I thought I was just coughing... For some reason even though I have a master bathroom I ran to the main one... And threw up. I threw up three times and tried taking a large breath in between. I literally couldn't breath. I was actually gasping for air and finally whatever weird bubble was in my throat popped or something and I could breath... I coughed and threw up two more times. I haven't thrown up my entire pregnancy, and now I wake up suffocating and puke a bunch???? What the HELL!? And I don't mean I was out of breath.... I literally couldn't breath. My poor husband was terrified because of how loud I was gasping for air. What in the world would have caused that???? 😰 Now I'm afraid to go back to sleep 🙁
