Mini pill and history of blood clots

I am currently taking the 'mini pill' after unsuccessfully having an IUD (was misplaced and caused too much pain) but I am concerned about taking the pill for too long because I developed a blood clot the last time I was on the estrogen/progestin combo BC pill. My husband and I maybe have sex 6-7 times a year...yes a year. He has low testosterone problems so the sex drive is non existent. Do I continue to take the mini pill to prevent any chance of pregnancy and risk developing blood clots or should I not take the pill and take my chances on becoming pregnant? We are not too worried about conceiving but we would like to wait a few more years for career path reasons. I am also experiencing some mild side effects from the mini pill.
