Also, it may also be accompanied by other symptoms such as blurred vision, headache, nausea, and pain in the upper abdomen. This is very normal to have.

In extreme cases, this can lead to retinal detachment and possibly blindness. So in this situation, you should go and have a conversation with the doctor, so he can tell what to do. Besides, swelling can lead to weight gain outside of the normal weight gain expected during pregnancy. Anyway, just be careful.
