Question 😩

So my period went off on the 4 , I’ve had sex almost everyday since probably skipped one day , but today I went to the bathroom later on in the day , and it was blood . I had mild cramps but didn’t think anything of it because my period just came off , so I’m not understanding why I’m bleeding or whatever , I put a pad on no blood really . I just just went to the bathroom , I whipped and no blood .😭😩 I anybody have a clue on why this is happening?
