Sign of doom? Or normal?

So I am TTC and I just peed and there was light pink spotting on the toilet paper. Pretty faint and maybe one or two drops at the end of my urine stream were pink. I am 15 days past first day of my period and my cycle was relatively short only about 5 days. This is normal for me though, my cycles tend to be short. I should be one day post ovulation if you use the 14 day rule so it seems like that would be impossible for this to be implantation bleeding. Should I be bummed? Is this a no go for a chance of being pregnant this cycle? Or is it no big deal? The bleeding only appeared on the paper the one time and hasn’t appeared any more times after that when I use the restroom
