Do i have a blood clot or is this just a leg cramp?

Posted at: 2014-06-09 
This evening i felt a dull ache in my left calf. I am moderatly active but i also take the birth control pill for irregular periods. I have been taking it for over 7 months and it hasnt been working well. One of the symptoms were blood clots. How can i tell if it is or just a muscle cramp?
You won't know for sure until it's too late and then you die
