Help! CT scan 4 days before finding out I’m pregnant

4 days ago I was in the room holding my daughters hands while she had a CT scan. They asked me before they started if there was a chance I was pregnant & I just instinctively said “no” because we honestly weren’t trying to get pregnant again. They put the apron thing on me anyway & one on my daughter & did the scan.

I just found out today I’m pregnant & now I’m worried!

Is this going to affect my baby??
