Hi, Elina, I'm sorry to say that, but yes, it is very common for pregnancy women to get DVT.
How common is it?
Venous thromboembolism (VTE), which encompasses both deep venous thrombosis and pulmonary embolism, occurs in about one in every 1,000 pregnancies. While those numbers make it a relatively uncommon complication, VTE crops up five to 10 times more frequently in expecting women than in other women of the same age — and 20 times more frequently in the six weeks after birth.
What’s worse, being overweight increases your risk of getting DVT.
The good news is that you won’t die because DVT and PE are treatable and even preventable among women who are most at risk.
Here are some suggestions for you to prevent DVT:
Getting plenty of pregnancy-safe exercise (as long as you have the OK from your practitioner).
Walking and stretching if you've been sitting for more than two to three hours (for example, if you’re on a flight).
Moving your legs while you’re sitting (raise and lower your heels and then your toes).
If you’re at high risk, wearing support hose to prevent clots from developing in your legs. You may also be asked to take a preventative dose of heparin, sometimes during the whole pregnancy or just for six to eight weeks after birth. You should consult your doctor before taking any actions.
