I think my period is gone today because a while ago I stopped bleeding and my period was last Sunday and it is Sunday and I think it stopped

Okay so it sounds like your period might be over because you stopped bleeding and it's been a whole week since it started. That makes sense because most periods last for about 2 to 7 days, so a week is definitely a normal amount of time for it to be finished.

Your flow changes a lot during your period. It usually starts out light, gets heavier in the middle, and then tapers off again at the end. So if it was already Sunday and you stopped bleeding, your body was probably just finishing up its thing. It's totally normal for it to stop and for you to be done for a bit.
