TTC after starting a new job

I recently started a new job, before I started my husband and I were set on TTC baby #2. This cycle we held back a bit but there’s still a chance I could be pregnant, if I am I’d be thrilled as this is what we’ve been wanting but I’m also scared to tell my new boss if I am. Any advice? Should I stop TTC until I’ve been there for a while if I’m not pregnant? So confused and nervous yet disappointed all in one.
