Scheduled surgery & found out im pregnant

So i had FINALLY scheduled a surgery i have been waiting for, did the blood work, and 2 days later found out im pregnant. i have an ultrasound scheduled in March, but according to my glow AF tracker im 4 weeks and 5 days. i was told not o tell anyone because its not confirmed until 3 months. Anyone else dying to tell people?! this is the biggest secret i have ever kept.
