Implantation bleeding?


I’m 4 days late on my period, I’ve been having sex about every other day the past three weeks and everyday during what I thought was my fertile window. I’ve recently been using preseed with my husband. This is our first month ttc. I just went to the bathroom and I wiped and saw this. It doesn’t look like how my period normally looks though. So I’m wondering if it could be implantation bleeding and that I ovulated later than I thought I did. Maybe my cycle is longer than I thought. I’m trying to stay hopeful but I know that it’s probably just my period bc I want to get pregnant so bad.
