Craving specifically for Dominos pizza

[SparrowNest]

I live in a part of London with plenty of excellent pizza places so I haven't ordered Dominos in years, but this afternoon I feel like nothing else will do.

Up until a couple of days ago I was suffering with quite bad sickness but it seems to have subsided and I'm ravenous now.

I'm only 10 weeks, is it usual to get cravings this early or is it just unrelated greed?

Could be a craving.
Cravings aren't all about the foods themselves, sometimes you will crave foods that are nostalgic.
E-g I craved the crappy foods my family ate when I was a kid: 2 minute noodles, instant mash potatoes, KFC, etc
I also craved boiled eggs and ate tomatoes whole.
Towards the end, anything salty or sweet.
But the cravings just feel like how you're describing, having an idea of some food in your head that won't go away.

Ahh that could definitely be it, we used to get Dominos as a very special treat when I was a kid. Thanks!
