I NEED HELP PLEASE

My period is due in a week, and I’ve been having blood in my discharge but it’s only been a little bit only when I wipe. It doesn’t even get on my panties. But I’m not suppose to be spotting or whatever because I’ve never spotted. I’m on birth control and I’m sexually active. Is this my period or could I be pregnant? I’m worried am I pregnant? Is this implantation bleeding or period?

I need advice please
