DVT during pregnancy

So I’ve had quite a bit of swelling in the past few weeks, some days in both ankles but most days just in my right ankle. I did some googling tonight and researching and apparently it could be Deep Vain Thrombosis, as I’ve also got pain in my ankle but haven’t injured it in any way and also have been light headed and had a lot of cramping in my legs/leg.

Has anyone experienced DVT while pregnant? If so, how serious is it and should I get it tested right away? If the swelling is still there tomorrow I’ll give my midwife a call.
