Do u announce to ur boss that you’re pregnant like week 5?

I did right after I found out cos I had to. The day after I found out I was yelled at by some superior at work, and I cried and wailed in the washroom at work. From then on I told my supervisor I couldnt tolerate the stress due to the news i just found out. Thankfully they excused me from being under that superior 🥲 Dont know if it really traumatised me or is just my hormones.
