How do I find a OB/GYN?

Ka

Preferably one that does monitor me closely because I have had previous miscarriage, I am over 35 yo, PCOS and thin lining? How do I find out they would be the kind of office that if I call them about an impending miscarriage they actually want me to come by and check me out and do something about it (meds, stitches, whatever).
