ALIFE 2 is a multi-centre randomised clinical trial to compare Low Molecular Weight Heparin (LMWH) with standard pregnancy surveillance in women with inherited thrombophilia (a blood clotting problem) and a history of recurrent miscarriage (RM).

Women with a history of RM (2 or more not necessarily consecutive miscarriages or intra-uterine foetal deaths), confirmed inherited thrombophilia and who are attempting to conceive or are less than 7 weeks pregnant (based on first day of last menstruation) will be registered onto the study.

Participants will be randomised to one of two groups. Participants in group 1 will inject LMWH once daily, starting immediately after randomisation. LMWH will be discontinued at the beginning of labour.

Participants in group 2 will receive no intervention in addition to standard pregnancy surveillance.
