10 weeks 6 days!

Okay, so March 15th I was in a bad car accident. I ended up with 4 broken vertebrae and some broken ribs.. I had X-rays, CT scans and the whole works. At the time, I didn't know I was pregnant. I found out at the end of April in the emergency room after I fell in the shower, went to ER to make sure nothing shifted. Dr asked me if I was pregnant. I said nope! He ended up doing an ultra sound and surprise! Terrible timing of course, but very thankful. I had a miscarriage last year January and it was terrible. My husband and I tried for about a year after that and well, here I am! Anyway, just curious if anybody else has been pregnant and had X-rays and stuff?? Doctor said X-rays and scans are only dangerous in large quantities.. but I have to admit I'm still nervous..also, I've been in bed ALOT more then normal obviously and I've already gained 9 pounds!! I do have a 10 year old and 8 year old already and ao many things have changed since then!! Lol!
