Loestrin 24 Fe and taking blood

I am a 29 year old female, who DOES NOT SMOKE!!!. I've taken birth control pills the majority of my adult life. However I took Loestrin 24 Fe a little less than a year...I was recently hospitalized for having DVT(Deep Vein Thrombosis) and Pulmonary Emboli....The doctors said the cause may be the birth control pills. Be careful with taking this oral contraceptive because DVT and Pulmonary Emboli is a serious side effect that can easily be overlooked by your doctor. For months I complained about swelling in the ankles and pains in my thighs. Until one day, my whole leg was swollen and was very painful while walking...I admitted myself into the ER the night before Valentines day!...I was then diagnosed with DVT and Pulmonary Emboli!!! The Doctors have taken me off birth control and now I'm taking blood thinners.
