I didn't tell them I might be pregnant).. and so now when I got home I used the restroom and it's a heavier spotting... almost as if I'm about to start my period... but I'm not suppose to for another 3 weeks... I been using the restroom a lot too... please help!

You need to be getting advice from a doctor if you are having unexplained bleeding, not looking for answers on a forum like this. Only a doctor is qualified to tell you why you have having this bleeding, anything anyone else says on here is only going to worry you more, or serve to falsely put your mind at rest.

You never said if you have done a pregnancy test to see if you are pregnant. You can do a test on the first day of your missed period or 21 days after you last had unprotected sex if you are unsure when this would be.

I would suggest doing a pregnancy test and contacting your doctor for further advice.

and in relation to your concerns about an x-ray = look at the information in the below weblink. The information on this site is evidence based so you can be sure of the accuracy of what they say.
