Help please

I am 33 weeks and 3 days. I've been nauseous and vomiting my whole pregnancy. I vomited earlier (about 2-3 hours ago) I couldn't see out of my left eye (it was super blurry and splotchy) and I got really light headed like I was going to pass out. I sat down had water and some peaches. I still felt crappy but my vision came back after about 30 min. I stood up and went to cook dinner for my son and I and now my vision is blurry again. I don't know if I had a vagal moment or what but it's been over an hour since I left a message for my dr. (He's not great at calling back) I don't know if this warrants a trip to L & D or if I just need to rest.
