A few minutes ago I had a really sharp pain on the side of me knee. I massaged it (though it hurt to touch) and tried to move my leg around. After a minute or so it went away.

I've been on Yasmin for 6 months, and because of ocular migranes, severe headaches, and depression, I decided to switch to Ortho Tri Cyclen Lo.

Was that a blood clot? Should I stop taking Tri Cyclen Lo right away?
