Period or implantation

So I’m wondering if anyone can help... my cycle was 32 days, then it went to 29 and 29 again last month. This month I’m 30 days in and I have been waiting for period and have had slight pink discharge. Every time I pee nothing is there unless “I go looking” for it then it’s like clear pink discharge? Wondering if this is a sign of my period coming or pregnancy? I have never had this before any period normally it comes thick and fast (age 23)
