I had unprotected sex almost two weeks ago, and was sent for extensive spinal xrays yesterday. As my period is only due by the end of the week, I'd not really considered the possibility of pregnancy until after the xrays. I have been fairly tired and moody, but have also been dealing with a lot of difficult situations in various areas of my life, that could be responsible for that. If I am pregnant, what damage could I have done the baby, and is it irreversible?
