How to draw a two (or even more) loop diagrams using Feynmf?

two loop correction to a 2-point function

I tried

\unitlength = 1mm

but it didn't work.

I plotted it using LaTeXit. The one loop diagram worked just fine so I guess it's the problem with my usage of Feynmf.

    Could you please make a full compilable example? – egreg Feb 15 '14 at 21:50

I have been able to solve this in a fashion:


This produces circles instead of egg shaped loops, and differently sized ones at that. I suppose one can fix the sizes, I'll update if I manage to get to that.
