I havent spotted.  the at home and blood pregnancy tests Say negative, however my doctor doesnt  believe this and neither do i. Im looking to check into a Ultra Sound but im told too early radiation can be bad for it?!!? this is my first time and my periods have been regular since i was 15. I am now 18.

What would you be doing that would have radiation? Ultrasounds use sound waves, not radiation to check for pregnancy and these can be done at any point in a pregnancy without problem. You can miss a period for any reason and not have to be pregnant. Have a beta blood test done to check the hCG in your body. If it's under 5, you're not pregnant.
