Spotting

So I’m new to this but have heard nothing but good things! Was needing some advice.. I’ve been trying to get pregnant with my current boyfriend for the past 6’months after a loss of pregnancy.. I’ve had no luck.. took me 6 years prior to this and have a son.. but we have been having a lot of sex in different positions lately and stay trying and never pull and no protection after a couple times of intercourse I noticed spotting I never spot and it was a week after a period??? Very light and only lasted a day or two don’t want to get my hopes up on implantation bleeding cramps and burning pee as well?
