I need some period help. So, I've had my period for a little over a year, and I've had it every single month. At the beginning of the year, I had mine in January as normal. In February, I didn't have one at all. But on the very first day of March, I had one, but it wasn't rly like a period. It was mostly just brown stuff, a little bit of blood, and it only lasted two days. For the rest of March, I didn't have one. I haven't had one in this month at all, either, and I know it's only the beginning, but I've had all the white stuff and all the PMS, but all the stuff ended, like, a week and a half ago, and it still hasn't started. Should I be concerned or should I just let it be?
