Hi girls!!! I'm 4 weeks along, and from the very start of the pregnancy I've had an insane craving for a Big-Bon, even though there's a ton of other tasty food at home! Is this normal?) Can I eat it?) I keep holding myself back all the time ? it's 12 o'clock at night now and I'm thinking maybe I should send my husband to the store after all and make my cherished dream come true ? thanks for the answers ❤️
