###Human: Is it normal to get sweating with black spots in vision during pregnancy? ###Assistant: Hello. Getting dizzy in a second trimester (after 20 weeks) of pregnancy is a normal phenomenon as pregnancy hormones especially Progesterone results in vasodilation of blood vessels and pooling of blood in lower limbs after prolonged standing or sitting. So do not worry about that. The only thing you can do is to keep yourself well hydrated and keep your legs moving while long standing or sitting and do not stand up immediately if you are lying down in bed.
