Couple of reasons for my question but with my first DC I told my GP, then when she asked which hospital I wanted to go to, I asked for one which wasn't the normal one for our area. I got that one, then decided to go private there anyway. In the meantime, GP had signed me up for the other major hospital in the area anyway and I had a nightmare with appointment forms coming through from them, me trying to cancel these appointments (spending ages on the phone to various departments, also wrote several times to explain that I didn't need them), calls from midwives shouting at me for not attending appointments and even social services getting involved at one stage as they said I wasn't going to appointments - yet I had all my pregnancy notes & was registered with another local hospital and a consultant having far more regular appointments. It all got sorted in the end but it was a bit stressful and annoying at the time.
For the next time, I will just go private again at the same hospital with the same consultant, so do I need to tell the GP? Is it a legal requirement?
