Menopause and blood clots

This is actually the wife!! I am 44 and since Oct '07 have not had my period but told after recent blood work that I am post menopausal. 3 hormone tests came back positive for this.  I am also juvenile diabetic for 38 yrs & take insulin and have severe coronary artery disease that included a quad bypass 1 1/2 yrs ago. 3 yrs ago, while still getting my period, I had my 1st heart attack due to a blood clot (it just happenedt to be the 1st day of my period).  Since Oct '07 (when I stopped getting my period) I changed an EKG and in January, March, April and May have had a blood clot each month.  The odd thing is that these mos are mos that I had symptoms that I would be getting my period but of course, never got my period.  I began taking lovenox in May '08 and have since started taking a 2nd injection a day but was told clotting can still occur.  The last 4x these heart attacks happened due to clots were at the same time I had my menstral cycle symptoms.  Is there any correlation between the 2 (something to do with hormones maybe?).  This month again I feel the symptoms and have worse than usual angina but if there is a connection then I will pay closer attention.  Many hanks.
