Im on progesterone pills (provera). They put me on them to stop the bleeding before putting the Mirena in and I have to stay on them for a few months while the Mirena settles or I could bleed out the Mirena. But what I wanted to say is I have a history of clots (pulmonary embolisms) and have a clotting disorder and progesterone pills do have a clotting risk it’s just not as bad as the estrogen pills. My gynaecologist said the risk of me dying from blood loss was higher than the risk of a clot so I took the risk but it still worries me and will be glad to get off them in about 5 weeks. Will have been on them 13 months.
