Hurt my knee and I need an MRI to rule out a tear and they are concerned about doing it because of my "possible" pregnancy (actively trying and all) My gyn office seems to think I'm okay cause I had a cycle 2 1/2 weeks ago but can't you still get your period when you initially get pregnant? Possible right? Not sure if I should get the MRI as scheduled, wait for AF, or insist on a blood test to confirm? Any advice? Thanks!
