Thanks for the query.
Physiological edema of the feet is common in pregnancy
That can be seen more in advanced gestational age
And some women may have red spots along with edema due to stretching of the skin layers.
So you once check for your blood pressure, urine albumin
levels and coagulation profile.
And take rest preferably in left lateral position with foot end elevation.
Restrict salt intake in food.
