V scan symptoms and conditions

I had been diagnosed in Dec 2007 with multiple blood clots in my lungs, I have never had blood clots before, after two c-sections, two pregnancies.
I was so short of breath thinking it was stress due to holidays and work that my doctor advised I should have a V scan of my lungs and that was when I was told both lungs were "peppered" with clots, I need immediate medical attention, I had to give myself Heparin in my belly for one week. I was off work for 3 months, I too almost lost my life, if I didn't have an angel on my shoulder which told me "something is wrong see your doctor" my children would be without a mother, my husband without a wife and I was in total perfect health. I pray and thank God every day for my life.
