Pregnancy-induced Asthma?

So, the last couple weeks I’ve been waking up in the middle of the night (and it’s happened a few times during the day) feeling like a I can’t catch my breath. I’ve never had asthma before, although I do get bad allergies so I’ve had trouble breathing before...but this has been really scaring me. I’ve always been able to calm down and eventually catch my breath, luckily, but I does leave me feeling pretty panicky. Has anyone else had this happen? I’ll tell my doc about it when I see her next...But just curious if anyone else has experienced this...
