Help please🦋

Had sex about3 weeks ago. He came in me and I dont use birth control .

Now I am never late for my period and it started the 28th where I had mild cramps , and I used a tampon just for incase. And I am a heavy bleeder.

And since the mild cramps I had light bleeding, but it doesnt fill up my tampons like it usually would... and When I wipe its kinda light aswell.

This morning.. I saw that it still doesn't fill up a tampon. Its kind of dry when i pull it out 😑

Sooo?? Please help. Should i test🤔🦋
