Pink semen, what's wrong?

It has only happened twice, and most of what I've read tells me not to worry and that it is probably nothing big... But it is definately scary. My semen has been coming out pinkish/red, I'm in no pain at all, it doesn't hurt when i ejaculate or when i go to the bathroom, and it isn't red or pink when I go to the bathroom either. I'm just trying to see if maybe you can pin it, or if maybe i should just wait it out and see if it keeps happening? I'm going to the doctor soon, either today or tomorrow, so they should tell me, but if you can get to me before then it would be fantastic.
