Pink Colored Semen

Hi All
I’ll provide some background. I’m a 53 year old with a family history of prostate cancer. A couple of years ago my brother was diagnosed with prostate cancer at 57 and subsequently had a prostatectomy and is doing well. Since his diagnosis I have been monitoring my PSA and they always came back within normal ranges. I was still not satisfied and wanted reassurance and underwent an MRI which resulted in finding a small 6mm lesion with a PiRads score of 4. The next step was a transperineal prostate biopsy where the urologist took 30 samples thus was in April 2025. The results were at ALL samples were clear and the next steps will be just monitoring PSA and possible symptoms. All went well with the procedure and the initial blood when urinating became less and less with the following weeks. To minimise the length of time to heal I stopped my aspirin for 4 weeks after the procedure. I didn’t ejaculate for approximately 6 weeks because I was fearful and when I eventually did it was rust colored and subsequent ejaculations became clearer with only brown specks which became less with time. Eventually by mid June the semen was clear like it was pre procedure. That is until a couple of days ago when all of a sudden when I ejaculated I noticed that it was pink in color and immediately knew that was blood. There is no blood when urinating, only in my semen. I just want to know whether others have experienced a reoccurrence of blood in the semen after it had all cleared and was clear for several weeks? Is this normal and should I be worried as I can’t seem to find any information about recurring blood in semen. I am on aspirin and that might be a factor.
