Pain in calf. The most common symptoms of a blood clot in pregnancy are swelling, pain, skin color changes and warmth in one leg. Pregnant women are at higher risk for a dvt. Smoking, obesity, recent surgery and family history are other risk factors. Some people are carriers of certain genes that can increase risk of DVT as well.

If you have unexplained swelling with or without calf or thigh pain then a venous ultrasound would be indicated to look for a dvt. Sometimes even a ct scan or mrv is necessary. The bottom line is, if DVT is considered, then proper testing is required.

Smoking, obesity, recent surgery, immobility, cancer, infection, certain medications (including hormones), and family history are all risk factors.
