First ultrasound tomorrow

Alyah

So I have my first ultrasound tomorrow. But my fiancee and I want to keep this pregnancy a secret so that nobody brings drama. My last pregnancy I didn't tell anybody who my son's father was so people would speculate on who it was. It stressed me so bad that I was scared I would go into labor or have miscarriage. I just don't know how I'm gonna hide the sonogram photos because I stay with my parents until we move. But the thing is I never told my family I was moving out or engaged so they think we're(me and my son) staying when they move(they're moving in a few months). What would u guys do if u were in my situation?
