Is this a normal pregnancy symptom?

I’m 31 weeks I just moved and I can’t get an appt with a new doctor because my old doctors office hasn’t faxed my medical records. Last night I went to sleep with a pressure in my head, I felt dizzy but I decide to just got to sleep.. I woke up 15 min later because I got a phone call and still had that pressure and decided to switch to my left side and try to sleep again but then I started bleeding from my nose after the bleeding stopped I still didn’t feel good but decided to go back to sleep and woke up the next morning feeling better. Has this happened to any of you??
