Help ? High risk pregnancy

I have PCOS , high prolactin and a history of miscarriages . I have conceived with clomid and metformin . My GP referred me to a gynochologist to look into these issues however he only prescribed me clomid and once i conceived he didnt help any further as to how to not miscarry again and said that my GP needs to refer me to Antenatal . Any tips or anything that will help me to carry full term ?
