I'm glad you've discussed them with your doctor and have some guidance regarding your visual disturbances. It seems in line with the direction we got.
Visual disturbances are one of those tricky symptoms since they are also totally normal. Non-pregnant people sometimes have visual disturbances- lil' squiglies, afterglow etc, and so do pregnant people. So our doctor always wanted me to report them, but also wanted me to keep the whole picture in mind. So a visual disturbance alone, when I felt good and my blood pressure was ok- we chalked up to the normal kind. But if I was having them a lot, and my blood pressure wasn't so good, then I should ping it at something more worrisome. But alone I could relax.
Glad you're continuing to have discussions with your doctor about your symptoms. Each case is unique and often care is crafted in conjunction with your personal history.
Keep posted as you're able. And yes, how far along now?
