Hi Julie, here in the UK the health system is a bit different from the US. If you need fertility treatment you can either go to private fertility clinics (which charge about $2000 per IUI cycle) or you are allowed a limited amount of attempts that are paid for by the state (which take place in our regular state-funded hospitals that look after the majority of the health care needs of UK citizens during their lifetime). However the state-funded hospitals are not open at the weekends for fertility treatments (at least they aren't in my area) so its a problem if your most fertile period falls over a weekend! We can't afford to go to a private clinic so we have to cross our fingers and hope that either the best dates are during the week or that a Friday or Monday date for IUI will still work.
