I'm 7 weeks pregnant, had a scan in the past few days and seen a heartbeat...she said it's measuring a bit small but she isn't worried as it was a strong heartbeat. I've got a 3yr old already and wondering when others told their kids? I'm waiting until 12 weeks to double check everything is alright...or would people recommend waiting longer? I'm not the skinniest so don't have the worry of showing anytime soon I don't think!
