sorry ajuba but wanting a baby should not be a reason good enough to go out and sleep with others.
Same thing happen to my work place, one of my colleague (not married in her late 30s) told me that she would to have a baby.
I do not like the idea, but there is nothing i could say, later on she was impregnated by her long time bf (a useless guy may be would never marry her).
But she as not muslim or desi, so it is different story.
