The current view on this has changed over recent years in the light of two studies. Both studies suggest that providing the woman does not have antiphospholipid antibodies, the low-dose combined oral contraceptive should not significantly increase the risk of a lupus flare. In the presence of antiphospholipid antibodies ("sticky blood"), there is an increased risk of blood clots with the combined oral contraceptive. Progesterone is generally OK in APS patients. The Mirena Coil is also generally recommended by the Lupus-In-Pregnancy Clinic at Guys Hospital.
