Doctors today!!

Gemma β€’ ttc#3 for 31 months 😒
Got my first doctors appointment today to try and start the process of finding out why we can't get pregnant! Got to be honest I'm so nervous 😞don't know what to expect. Can anyone give me the heads up on what sort of things I can expect?? I know it's a process to go through with bloods etc but just wanted some advice!! Thank you in advance ladies 😘😘
