Do you have, or have you been tested for, gestational diabetes? Vision changes can be a result of large fluctuations in blood sugar. Are you adequately hydrated? Dehydration can cause some interesting symptoms like you are describing, too. Be sure to bring this up to your doctor.
I've had floaters for about four years now due to extremely high blood pressure. It's under control now with meds but unfortunately the floaters stayed. I'm 6 weeks and 2 days today....so far no worse than they were....but it could be something to do with yours.
