Hi all I'm Day 4 after FET (4th IVF attempt) and I've had a persistent chesty cough since the transfer day - can the coughing affect the chances of implantation? I spoke to my consultant and she was a bit non-committal and wouldn't give me a straight answer, which has made me paranoid!! Speaking to GP in the morning but until then I'm sweating!! Does anyone know if coughing will have an impact on implantation success?
