Hi I am 23 years old and I have always had problems with my cycle. My last cycle was from April 23 - 27,2010. My cycle motsly comes on between the 27th and 29th day and I have not had a cycle yet. I toke a pregancy test on May 24th because I had to get an open MRI done and it came up negative. I have not had any signs that my cycle is about to start. Is it to be pregant? If so was it bad to have an open MRI. I really wont be mad if I am pregnant I just don't know if the open MRI was harmfull. I go to the OBGY on June 14th should I wait untill I go to let them run another pregnacy test if I don't have my cylcle before than. Please help me because I don't want to hurt my baby if I am pregnant.
