birth control
"After having my IUD removed, I decided to go with a short term birth control so I could try for a baby within the next couple years.  It got put in in October 2016. By mid December I was having unexplained bruising on my legs, symptoms of bronchitis/asthma, weakness, and coughing up blood. In February 2017 I was finally diagnosed with Bilateral Pulmonary Emboli and congestive heart failure and was hospitalized for a week. I was referred to a hematologist to figure out why I got the clots, being that blood disorders or heart disease does not run in my family.  The Dr finally concluded that it was due to the new birth control I had so it was taken out by March of 2017. I guess I was the unlucky 1 in 100,000 to have severe side effects."
