Warfarin Sodium and horrible headaches

In July my calf hurt for over a week I went and had it checked out and they found a small DVT I was sent home and prescribed Lovenox and taken off my birth control. The next morning I had trouble breathing and went to the ER I had multiple PEs in both lungs. I was in the hospital for 5 days and sent home with a non-therapeutic INR, Lovenox shots and warfarin sodium. I have to regularly increase my dosage I am now up to 15mgs 6days a week and 10 the 7th day. I have recently started seeing small unexplainable bruises, even though my INR is still not and only has been for a short time since my release from the hospital. I have had severe chest, leg and other body pain. I have been to the ER so much I have just stopped going. I have horrible headaches and fatigue especially after they re-up my meds. My periods have been off the charts as well. I think I am done with this and I am really considering taking myself off the meds
