Do they have a feeling or really look swollen, i.e. when you press you have a feeling the swelling? I did read this

Women who experience any of the following symptoms while taking Mini-Pills should phone up the clinic right now:

Abdominal pains (severe)
Chest pain or shortness of breath
Headaches (severe)
Eye problems, such as blurred daydream
Severe leg or arm distress or numbness

Now you did not articulate you own numbness but still I would phone my doctor and give an account him/her in the region of this, its not a typical side effect.
