It takes 2-3 days for the sperm to meet the egg, 2-3 days for the egg to travel down the fallopian tube, 1-2 days for the fertilized egg to implant, and another 2-3 days for the level of hcg to build up enough in your system to get a positive result on a pregnancy test.
Or, it can be a symptom of a stroke that's already occurred. Vision complications due to a stroke depend on where the stroke occurs. The majority of visual processing occurs in the occipital lobe, in the back of the brain. Most strokes affect one side of the brain. If the right occipital lobe is injured, the left field of vision in each eye may be affected. A stroke that affects the left occipital lobe may disturb the right field of vision in each eye. Rarely, both sides of the brain are affected, but this can result in blindness.
The symptoms depend on both the severity of the stroke and the region of the brain it damaged. Perhaps one leg does not seem to work well, or an arm feels weak. People may have double vision or a partial or, rarely, complete loss of their field of vision.
