Loestrin 24 Fe and lungs

I am 29 years old and was taking Loestrin 24 Fe. Six days after taking the pill I started having severe pains in my right leg and trouble breathing. Come to find out about two and a half weeks later I had developed blood clots in my leg and had traveled to my lungs. Thank God it was caught in time. I spent 6 days in the hospital on total bed rest, they wouldn't even let me go to the bathroom. I was on blood thinners through the IV and in pill form. I also had to have a blood transfusion because of the periods I had two weeks apart from each other, which were extremely heavy. I went through 80.tampons and 48 pads. The ER doctor said if I had not come to the ER that day I could have died that night.
