Sorry you are having problems. The options to estrogens for birth control for people who have had previous clots or have had a thrombophilia are: progestogen only pill, progesterone implants, coils (I find the coils such as the Mirena coils particularly good), and mechanical methods. The only method you can't uses is the combined oral contraceptive pill.

Many thrombosis experts would offer the combined oral contraceptive pill if the woman had no other option and they were taking long-term anticoagulation because they had already had a clot.
