This is my first time posting, but I’m not sure where else to turn...

So this cycle, my period started on time. But it wasn’t like my normal period. It lasted for 3 days & it was extremely light when I normally have an extremely heavy and cramp filled period. But since it stopped, I’ve had brown discharge every time I wipe. So I’m a little concerned as I had an extremely light “period” for 3 days when my period is normally heavy and lasts 4. Like I wasn’t even filling a tampon within 5 hours. And now I’ve had brown spotting for 3 or 4 days.

If anyone’s had any experience with this before, or knows what could possibly be going on I would really appreciate it!
