Lifestyle issues symptoms and conditions

I'm 39 and have been on Coumadin for about a month. Was diagnosed with DVT in right calf after taking Yaz birth control for only about 4-5 months (no other pre-conditions - I'm a non-smoker, fairly active, not overweight, no recent airplane trips or long car rides.) I was on Yaz to treat severe problems with my period which has been the case since I was a teenager, but I was tired of having to call in sick to work every month, and had hoped Yaz would eliminate that problem. I had been on other BCPs when I was in my 20's, and never had any symptoms of clotting, so didn't think that it would be all that risky to try again, despite me being slightly older than the typical woman on BCP. Obviously, I am not taking Yaz anymore, and will not be able to take any other hormonal therapies for the rest of my life. But I guess that's minor compared to the risk of developing PE from an undiagnosed blood clot.

Anyway, I've been noticing I've been getting sudden, severe headaches since starting the Coumadin. I have a history of migraines but I usually only get one or two per year at most. Now I've had what feels a lot like a migraine twice in a matter of a couple weeks. My husband has also commented that I've been irritable and acting "spacy".

My INR has also been all over the place. They've been alternating me between 5 mg and 7.5 mg per day. For the first few weeks I was right where they wanted me - between 2 and 3, but then last Friday my results were 4.6!! Way too high. I go back this afternoon to see if anything's changed over the weekend, after skipping a dose and then doing 5 mg Sat. and Sun. I do hope they can find the right balance and don't have to keep tinkering with the dosage. I'm wondering if that's what's contributing to the headaches. Maybe if they can stabilize how much I'm taking from day to day, my body will adjust.

I wonder if anyone "official" is tracking the number of DVT/PE patients that can trace their onset of symptoms to Yaz. My sense is that this is a much more serious and prevalent side effect than their marketing dept. would like to admit.....

Our daughter spent her 21st birthday in ICU, Sunday the 13th. I took her to the ER with shortness of breath, chest pain and nausea on Saturday afternoon. She has been on Yaz since February with only the mild symptoms of: loss of apetite, mild nausea and some abdominal cramping. She was put on this BC to regulate her periods and relieve menstrual pain as well as excessive dark facial hair growth. All 3 of these were relieved by Yaz.
She has now spent 1 week in the hospital (2 days in ICU) and will be on coumadin for 3 to 6 months due to a very large pulmonary embolism (size of my knee cap) that was putting the right side of her heart in distress. She also has multiple clots in her right lung.
I am shocked to read through this website and see all that has happened to so many women. She can never take oral BC again in her life. There are no blood test results that indicate she was even predisposed to this type of reaction and is not family history.
