MRIs and pregnancy

I'm finding it hard to find this info on Google.

I know MRIs are pregnancy safe (X-rays are not)

I didn't have contrast. It was of my pelvic area.

If I was pregnant would it have been seen on a MRI? I would have been between 12-14 weeks (based on when I last had sex, whilst on placebo pills)

If pregnancy was seen, would it had been put on my report??
