Baby poop question (TMI warning, pic attached)

Not a lot of traffic here I know, but I can't get a doctor's appt til tomorrow at the very earliest (bloody nightmare getting one round here) and the health visitor hasn't called me back, so I guess it's here or nowt for now.

So this came out of Mr 14-Weeks today and obviously the dark coloured bit had me Googling and everything's going dark=blood, probably from cracked nipples - but he's a formula baby. And it's not really black, more dark brown. And there's quite a bit of dark, so would seem a whole lot of blood - you'd think there'd be some other signs of something very off in that case! I'm guessing just one of those weird things but while I wait and worry for the doctor to finally get in touch... anyone else had something like this?

He's entirely fine in himself, eating normally, laughing away, napping fine, generally awesome.

Ah, very glad to hear it! I don't remember anything similar with Boy 1 so it had me worried, I remember the poop going mad once we weaned but before that he had pretty consistent colour/texture, so this from Boy 2 threw me a bit. But I'm glad someone else has seen similar and all been well! Thanks
