I am 29 yr old and a mother of 3.3 yr old son. now we are planning for second child. but due to my husband's job we are living together. (he got transfer in remote area and we don't want to take our child to that place). he come to meet us for 1 or 2 days but that meeting is not working (can't conceive). now one of our friend suggested us to take medical help and go with IUI. I don't know what it is, any one know about it then please help me out.
