UK mamas only please!

Hi all just curious has anyone been for test for fertility? And How did you all go about it? Did you just book a appointment with your gp? Also when Iv done online searches it’s all fertility clinics that pop up, so do they refer you to a clinic? As Iv been looking at the prices of even a consolation and seems pretty expensive 🤦🏻‍♀️ or do you get sent for test on the nhs? 🤷🏻‍♀️ sorry might seem like a stupid question 😂 just want to know what I’ll be getting myself and husband into if we go ahead and speak to someone about our trouble conceiving.. don’t want to end up at one of those privet clinics and being left with a pretty large bill 🙈 thanks all 😌
