Ask Dr Ruth

Dr Ruth Curson answers your medical questions about egg and sperm donation. She recently retired from her job as Specialist at the Assisted Conception Unit, King’s College Hospital, London.

Dear Dr Ruth

I became an egg donor 18 months ago. Since then I’ve been trying to get pregnant and had a miscarriage. My periods are now regular but my cycle has changed to six weeks apart. Could the egg donation have caused this?
