For the first few days, you may notice blood clots and tissue passing, but this should taper off after about a week. It will take about four to eight weeks for your regular period to return. Mild exercise following an early miscarriage is usually fine, but check with your doctor.
What is the decidua of the placenta?
The decidua is the specialized layer of endometrium that forms the base of the placental bed. The corpus luteum of the ovary (and later, the placenta itself) produces progesterone that induces endometrial stromal cells to undergo cellular modifications and vascular alterations termed the ‘decidual reaction.
Can you pass decidual cast and still be pregnant?
2 Decidual cast formation can be associated with ectopic pregnancy or, less commonly, exogenous progesterone. Decidual casts have been attributed to use of oral contraceptives, injectable progesterone, or an implantable progesterone delivery system (Nexplanon).
Does Decidual reaction mean pregnancy?

Within the pregnant decidualizing uterus, coordinated vascular, immunological and stromal cell changes occur.
How big should a decidual reaction be during pregnancy?
A thin decidual reaction of less than 2 mm is considered one of the features suggestive of an anembryonic pregnancy 2. A decidual reaction in some situations can also occur in an ectopic pregnancy 3. 1. Turner RJ, Carroll BA. Ultrasound appearance of decidual reaction in the uterus during normal pregnancy.
