Pregnant and new opportunity

[Newmumtottenham]

Hey!
I’ve been offered a new opportunity at work to cover a client for a member of my team who is going on maternity in Jan. They don’t realise I am also pregnant and due in July next year. I have no intention of telling them yet but I’m worried about messing them around when I do tell them in Jan/Feb and need to get cover again... am I worrying unnecessarily?
