Hi guys

So I had my period July 30-august 12 then I had unprotected sex August 13, couples days later sex again on Aug 21 on the 22 -23 I was spotting medium sometimes light could it be impatlation bleeding (pre pregnancy) or UTI or I was having sex to rough? Can some help on what going on? Should I take a pregnancy test . These is how my bleeding comes out and it only happens when I wipe. Am I’m having a second period?

I do have pcos and irregular periods that last 10-11 days length 28-29 days

My pre mom app say I’m ovulating Aug 29

My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says ovulation Aug 13-14
