Help, dvt?

Have any of you experienced a dvt? If so what were your first symptoms? Early yesterday I noticed a pain on the top of my knee, it hurt to sit criss cross and it hurt to put pressure on it. This evening I’ve noticed my calf now has a weird achy feeling and so does my inner thigh. And my leg is somewhat tingly. I’m going to call my doctor, but it’s Saturday and nobody is available.
