We have been ttc now for over two and a half years, we are nearly ready to start IVF but have been told I needed the HSG test done first. I rang on the first day of my period in dec to be told I couldn't get an appointment and to call back in Jan. I was due on on Fri and still have no period, I am regular as clockwork and have done two pregnancy tests and both are negative! The one time you want your period and it doesn't come! I can't book this test until my period arrives. Don't know what to do now?
