@smcg1 you don’t have to tell them until 15 weeks before the due date. I will be leaving it as late as possible as I suspect there are people in my team who will not be very supportive.
I did a digital test yesterday, which said 3+ (as it should) but I can’t shake off the worry as still no symptoms, aside from very light and very irregular cramps. Only a few days until my private scan, so just need to wait and see.
