Please help!!!

Shaylyn • Our #1 is due in Janurary 💕
I'm late for AF so I may/may not be pregnant. If I am I want to keep it to myself for a while as I've had two very early miscarriages. Not testing till Friday ... The dilemma, I believe I've broken my finger .... What do I do?? If I get an X-ray on my hand will it harm a fetus(if there even is one) ??? Do I tell the technician I may possibly be pregnant, but will they test first or just take my word?
