I started "yasmine" birth control pills a few months ago. Everything was fine until about 3 weeks ago when a small lump appeared in my leg behind my knee, about the size of a walnut just under the skin. It was sore and as it went away the skin was purple as if blood was under the skin.

Now, there is another one on my hip, about the size of a marble....

Yes, I am seeing a doctor tomorrow but wanted to see if anyone else had experienced this problem.

Thanks
