My mother took it, I was conceived on clomid. 
Myself and OH tried for 1.5 years, and in that time had tests which said I probably was not ovulating at all and OH had less than 1% of the sperm he should have, and that what he did have was deformed or lazy. We would only conceive on IVF.
Anyway, I'm now 29 weeks pregnant naturally.
Look, when I was TTC I was really depressed - so bad I had time off sick. I really, really understand how stressful and horrible the whole experience is. It is grief, in a way, but very few people understand. I was extremely lucky. And it would really annoy me when people would say "just relax and it will happen". People say that's what happened to us - we stopped trying. But I don't think it is. It is luck, it is nature, and it sucks sometimes. We have no control, including by relaxing.
But do not give up hope! Do not let anyone do that. No matter how it happens, if you want to be a parent, you can. It may not be how you expected, but it will happen. We would be boring if we were all made the same.
