Can someone please help... Dvt?!

so i woke up yesterday morning with this pain down my right thigh. And it still is there today. Its also spasming a lot as well. like 4 days ago, i went to the hospital and had full blood work done, and a d-dimer test, and it was all good. I have a strange phobia of getting a blood clot. Could I have one even though i just had that testing? i have no risk factors, or hereditary causes to get one. im 22 f with no medical issues...
