TMI question

So about 5 weeks ago my bf came inside me on accident he claims... anyways two days later I notice I was bleeding a little when I wiped so I used a panty liner and there was nothing so I didn't think anything of it...so fast forward five weeks later My period is 5 days late the other day I went pee and when I wiped there was reddish brown blood like discharge like the kind I have when I'm finishing my period and today I have the same thing idk what to think or do

*update* negative test I guess I should just wait for my period to start next month
