Aishu,
I have a doubt here.Sorry to threaten you.Has the shape of your uterine cavity been analysed?Is it normal?
I also would want to know whether your LH,FSH and prolactin levels are normal.
IUI with no sperm wash is not at all acceptable.Just make sure about this thing.It bothers me a lot
Unblocked tubes and good quality sperms are a boon now a days.Hence all your worries are temporary.
Good Luck!
