We are doing TSI to start with as DH has 'great looking swimmers' apparently. If this doesn't work after a couple of goes we will move on to IUI, though DH doesn't like the idea of this - he has major performance anxiety over the whole providing a sample! Hopeless! Af is being a bit of a cow but if it is as usual only usually last one to two days of being this way. Hope you are not going too crazy in the TWW.
