My period has been acting weirdly. About a month and a half ago, it was discharging a think brown paste thing for a month, then I got my actual period. It subsided for a day or two, then the brown stuff came back, went away, each time for just a day or two. Then it had stopped for about a week, but I masturbated by clitoral stimulation and then something similar to my period started happening later that night. This is where I'm currently at, but my last period was 2 weeks ago.

As background, I am 19 years old and have never had a regular menstrual cycle. I could go 4 months with no period, but it never came sooner than 4 weeks. I have never had sex nor has anyone other than myself touched my private parts.

I just want to know if this should be of concern. The brown stuff has happened twice before, but never this long, only a week or two tops each, and then went away.
