when I went with my cardiologist he said that birth control pills produce blood cloths, bruises are a symptom of bad circulation. It is also a symptom for more serious illness like leukemia, I do not mean to scare you with that, serious illnesses have often no symptoms. As a prevention I suggest you to make a regular blood test to see your blood count and talk to your doctor about birth control pills.
Bruises generally (but not always) signify a clotting disorder. It could also signify a fragility in the small veins that run through the body.
The reason you have to take this seriously is that there is a possibility that blood leakage could take place elsewhere. If you bumped your head, for example.
The problem could be as simple as a vitamin K deficiency. It could be related to your birth control medication.
Don't be concerned about telling the doctor what specific tests to take. They will know what to do.
Put "seeing a physician" at the top of your list of "things to do".

Yes, birth control pills can cause bruising. Consult a gynecologist and see which other pill you can take that will not have bruising as a side effect.
If pills are not the cause and changing them do not help, then other causes will have to be looked into. Deficiency of Vitamin B12, folic acid, or Vit K could be the cause. They could also be fragile spider veins. The bruise like things could also be petechiae, which are pinpoint-sized red dots under the surface of the skin. They can result from autoimmune disorders, such as lupus or rheumatoid arthritis, bone marrow disorders such as leukemia, inflammation of the veins, as a side effect of certain medications. A comprehensive investigation will be required then keeping all the points in mind.
Please let me know if there is any thing else and do keep me posted. Take care!
