Re: Had X RAY - now I think I'm pregnant!
Well, before worrying yourself, go out and take a test and see if it comes back positive or not.
I would think if you got X-rays before finding out you're pregnant, it probably won't do much harm to the baby, though you do want to mention it to your doctor. I have read numerous stories of women going out on drinking binges or taking no-no medications or getting an X-ray before finding out they were pregnant, and their babies turned out fine. Obviously, you don't want to be having X-rays if you know you are pregnant unless they're absolutely necessary, but I doubt you will have done lasting harm to the baby if you are pregnant.
Go out and get a home test since your period is late or see the doc and get a blood test done.
