Spotting...my period or implantation bleeding????

Queen
Today I noticed that as I wiped I had a bit very small amount of blood I am wondering is it my period because it is only 2 days away or could it be implantation because I have been trying to conceive and most definitely had sex during my fertile window ...I took a pregnancy test on yesterday but it was negative so I'm hoping we are having a baby but confused on what's going on here.
