Normal symptoms for 29 weeks?

Vanessa
I'm 29 weeks and 5 days, FTM, and for the past few days I've been experiencing these symptoms:
Headaches
Nausea/vomitting
Spot of light in vision
Shortness of breath
Are these normal or common during the 3rd trimester?
I'm waiting to hear back from my doctor so I wanted to hear what you guys think until then.
