I'm 31 weeks pregnant and today I've been feeling kinda off. I feel light headed, I have a migraine, and I've been seeing a lot of floaters in my vision. Most of these things would be red flags. The problem is I have chronic migraines and I have, in the past, had trouble with this stuff just from that. How do I know when to call the doctor? It's Sunday and I really don't want to end up in the ER for hours just to be told it's my chronic issues. Thoughts?😕
