I haven’t RTFT, so sorry if I’ve missed anything important, but I had to jump on and say I think it is absolutely fine that you told your work - you (and every woman) should feel able to tell whoever you like at whatever stage you like.
I had a MC at 6 weeks last year and only me and my DH knew I was pregnant. I ended up in A&E in the worst pain of my life (my body got completely carried away in its efficiency to end such an early pregnancy). I then had to email my boss (who is kinda a mate too) explaining I was in hospital, but ok, but also not that ok and would probably be off the next day too. I didn’t explain why I was in hospital as it felt too personal and awful to share. So I ended up feeling awkward and worried they’d think I was skiving, while also heartbroken. I also went back to work way too soon (2 days later), which really F’d me up mentally. I ended up having a little meltdown to my boss a few weeks later - turned out he had guessed ehat had happened, and he was incredibly supportive.
I also had to tell my mum that I’d been pregnant but MC’d, as she could tell something was up when I next spoke to her. I didn’t feel I could just call from the hospital and sob like I wanted to.
When I fell pregnant again a couple of months later I told my immediate family straight away. I told my boss at 12 weeks still but as he knew about my earlier MC by then I knew that if it happened again I would feel comfortable telling him and asking for the time I needed to heal.
That second pregnancy is now a very vocal and bouncy 9 month old 🙂
It’s your pregnancy and your body - don’t let anyone tell you how and when you should talk about it. Congratulations and all the best for a happy and healthy pregnancy and birth!
