Baby will be fine! It is long-term exposure that will cause the most damage. Definitely left your employer know that you can no longer participate.
BTW, one of my husband's cousins is pregnant and is a radiologist. She takes X-rays all the time and while I'm not sure if she's still doing it, just wanted you to know that she was probably exposed as well but, as a medical professional, is not concerned.
When I was 3 months pregnant I had to get X-rays of my hand because I slit my thumb wide open (had to check for nerve damage) and my daughter was born full term and perfectly healthy!
There shouldn't be any issues with the baby since you wore the lead apron. Just be sure to let your ob/gyn know.
I had to have several x-rays in my last 2 pregnancies and both of my daughters are healthy.
When I was pregnant with my son, I broke my femur! (The bone between your elbow and shoulder.... ouch!!!) There was no way I could avoid getting xrays... I was covered in the lead gown. I gave birth to a very healthy little boy! There should be no worries.
you shouldn't have any issues if you were covered. However you need to let your employers know that you are pregnant to prevent those potential hazards to your baby.
