Hi. Your GP is following protocol and you should be on the 2-3 week pathway for the scan to check the womb. R U still under the care of the Hospital? Do U have a family history of blood clots or is there 'no known causation'?
Could U take a cancellation appt if someone can't attend to see the Gynaecologist, if the Hospital is close to where you live, it may be worth while ringing to leave your details.
All these issues are worrying. Let us know what support you have too.
