Insomnia

So I found out I’m pregnant 4 days ago. I wanted to wait to tell my family because it’s still early. Only issue is the past four mornings I’m waking up at 3:50am and not able to go back to sleep. It happens to me when I’m under a lot of stress or having anxiety and I’m wondering if it’s cause I’m keeping this big secret. Not sure what to do. Just tell my family and hope I can finally sleep again or wait? I’m already exhausted and idk if I can keep this up waking up so early.
