Pain in your calf, thigh, groin or when you breathe - Deep Vein Thrombosis (DVT) or Pulmonary Embolism (PE)
Blood usually flows smoothly through all blood vessels. Occasionally, however, blood can form thrombosis or clots in the big veins. These blood clots can also be called venous thrombo-embolisms (VTE). This is a collective term used to describe both Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE). DVT is not common in pregnancy.
But you're more likely to develop DVT at any stage of your pregnancy and up to 6 weeks after the birth than people of the same age who are not pregnant. Please click here
