FTM, got a positive test 2 days ago. How do you cope with the uncertainty and not being able to tell people?

My husband and I (29M and 28F) have been TTC for 3 months and were very excited and pleasantly surprised when I got my positive test (14 days DPO).

We’re both very aware of the risks of miscarriage, and we keep telling ourselves not to get too excited, but I’m struggling to find the balance. I keep on getting this paranoia that I’m about to start bleeding at any moment, and not being able to tell friends or coworkers isn’t helping.

How did you maintain a healthy mindset in the first few weeks?
