abnormal uterine bleeding
"I took Quasense as prescribed for less than 2 months.  I had a life threatening Pulmonary Embolism.  Almost all tests are complete and all specialists say it is caused by the birth control.  Please be careful if you are taking hormonal birth control, please ask your Doctor to do a clot risk assessment on you and KNOW THE SYMPTOMS of DVT/PE.  I went to the ER with chest pain, cough and shortness of breath.  I was told if I had not gone I would be dead.  Just be careful.  Estrogen can increase your risk of blood clots.  Know the risks, know the symptoms."
