Has this ever happened to you?

So earlier this week I just got done having my period for almost a month....ugh it was ridiculous. But you see it wasn't anything like my normal one either. For every day that it happened for the first 2 weeks its was like a brownish discharge, like it would be if I was expecting to come off of it and then the last 2 weeks it went to a more reddish color. But the whole entire time I was on it it was lighter than spotting. Like it wasn't enough for a pad let alone a tampon. So I mainly used panty liners, but even then it wasn't enough for that. Like I only spotted here or there not through out the day. And I know for a fact I am not pregnant and I am no more stressed out than normal. But now this app is predicting my cycle to start up again... so my question would be did this ever happen to anyone else and how soon did you get your next cycle? I seriously am not ready for it lol, since I just got off a month long one. And there is no changes to my medications that I take every day. And nothing really to cause any alarms, I didn't even get my normal back aches, break outs and bloating. Thank you for your advice and input, I lost my insurance and trying to avoid going to the doctor for something that they would call "Normal" or "It happens to every woman at least once" explanations.
