for sure, pregnancy will delay everything as they wont agree to do the x ray. in my case, I got my medical done without an x ray. no doctor agree to send me to the x ray. I wanted to do it on my own consent and let them cover my belly with apron but all the doctors refused saying that it is not recommended during pregnancy so I don't have any choice other than to wait till I deliver and this will delay my application for 4 more months . so think twice b4 getting pregnant
