No. There are no known risks associated with progestogen and blood clots. The only contraceptives you are not allowed to take because of your mum’s blood clots are those that contain oestrogen. This means the combined pill, the contraceptive patch and the vaginal ring. You can safely use the progestogen-only pill (POP) or any other progestogen-only methods, such as the intrauterine system (IUS).
