First appointment with fertility specialist. what to expect?

got my first appointment with the fertility nurse specialist tomorrow and im feeling a bit nervous. my partner has been checked out by a fertility specialist (urologist) and been given the all clear. im 29 years old, i have already had a blood test arranged by my local family doctor in december to check i was ovulating which i was. i have regular periods evey 28 days and no period pain ever atall really, period lasts around 3 days. i dont really know what to expect? waht will happen and what may happen at future appointments? also is it ok to see a fertility nurse specialist other than a consultant?. thankyou x
