Help me out 😩

Hi moms! Sooo, kind of an odd question but also panicking. So I started my period on the 4th & somehow I’m still on it?? So typically with my period, I’ll bleed for a few days then get nothing and a couple days later it’ll come & finish up. So this time around. When “I thought” it was finishing up *it’s like the medium rare color of blood* which is normal for me. However, it hasn’t finished yet. I’m not bleeding a lot, literally not even enough for a tampon. But I’m curious why this is happening. I should also add that I had sex when I thought it was finishing up. And now it’s not done? I’m so confused bc I got the browning color when I thought it was done & now I’m getting a deep reddish color but nothing significant. Help me out 😩😩 I’m panicking
