We have 1 ds aged 7 been ttc for 4 years. Have now been offically labelled - as inexplained secondry infertility. (such a scary big label)Have seen consultant this week who has talked us through iui, he is just waiting for us to say yes then its pills injections then that 2 week wait. Every month when af arrives its disapointing but after treatment I don't know if i'll cope if it doesn't work. Has anyone else tried iui? How many attempts before a bfp?
