How do y'all get through the 1st trimester without telling everyone?

Seriously, i just found out 5 days ago, im 4w+4d, so exhausted i could sleep standing up, the nausea hit like a ton of bricks this morning. I have a fairly physically demanding job and i just have no energy. All my coworkers are noticing and asking if im okay. Am I just supposed to tell everyone for the next 2 months tjat im just tired or not feeling well?

To be clear, im not worried about any repercussions from my job when they do find out, they're a pretty family-focused company. I just feel like I'm not far enough along to really be telling people

Edit: thank you to everyone who shared their experiences. I have shared with a couple coworkers that I'm close to already, but i do feel ill need to share with more sooner rather than later just because I'm so sluggish and nauseous and it must be really noticeable because even people I only see a couple times a week are checking on me, and I am barely getting through my days right now
