Spotting? Implantation bleeding?

Nancy

Hi everyone, I am almost 31 and trying to conceive #1, cycle #2. I ovulated on October 3rd and period would be due October 17th. Just noticed some brownish discharge when after peeing today and yesterday I had some mild cramping. I've never spotted before and I am wondering if this could possibly be implantation bleeding? Has anyone experienced this or have any insight? Thanks and baby dust to all!!
