For Obstetrics and Gynaecology I used Obstetrics & Gynaecology by Impey and Child which was recommended to me by an F1 and it seemed pretty good. My medical school included sexual health and breast health in O&G, so therefore my notes also include these things- although obviously STDs and breast cancer are not solely female diseases!
Doing a rotation in O&G means that most of the time you see things going wrong, as (at least in the UK, I don’t know about the rest of the world), midwives tend to be in charge of more straight forward births. It makes one realise why maternal and infant mortality was so high before modern medicine; seeing haemorrhaging due to vaginal tears, newborns being resuscitated etc are sights that will never leave me!
For exam purposes, I would say that the key things to drill into your brain are the ins and outs of different types of contraception. Examiners (both for writtens and OSCEs) love giving scenarios where you have to recommend a particular type of contraception, inform what to do if a lady misses a pill, recommend a particular kind of emergency contraception etc. Therefore learn all the key side-effects, missed pill rules and windows for emergency contraception.
