Delightful subject, sorry, but what are others experiences with teething and a change of poo colour?

Olivia's poos have changed from that pumkin colour to a murky green, & I am thinking it may be because of teething?

She is breastfed so poos only about every other day, and these weird coloured poos seem to have started this week at the same time as her cheeks are a bit red and I am sure I can see a little tooth beginning to pop up in the middle of her bottom gum........

Any ideas?
