Is Light Pink Semen A Cause For Concern?

With my girl friend last night and I ejaculated a light pink colored semen. I have no pains or other issues. No burning, orgasm felt normal, no urination issues and my urine is between clear to very light yellow. I have low blood pressure (117/72) and a resting pulse of 42. I exercise regularly and eat right. Any cause of concern for this light pink semen?
