Planned Parenthood prescribed Ortho Novum 1/35. I asked if this would be a safe medication for me. I was told I would be fine. I indicated a family history of DVT (blood clots). Almost a year later, after a swollen calf for 8 months and difficulty breathing (reported to nurse practitioner) I ended up in the ER with a pulmonary emobolism. How could this group of symptoms, family history and medication scenario be missed. Note to consumers: BE CAREFUL!!! Don't rely on your doctor!!!
