Period issues

So, just to start off, when I got my first period (about 3-4years ago/ I had just turned 12) I only had it for one month (July). I then didn’t get it again until the following September. After that, my period was pretty regular, not always around the same time but regular. Then, about a year ago (in the summertime), I smoked weed a few times (over the course of a few weeks). Though, towards then end of last year I began to do so more regularly, and continue to do so regularly now. I never had a problem with my period when I first began to smoke more regularly, and I did get it in June, for about 4 days (my cycle lengths also vary at times). In July, I had got what at the time I thought was my period (for about 3 days) but it was very light, almost a pink so i believe now it was just spotting. Though, my period has been irregular before, I wasn’t sure if the fact I’d been smoking more frequently had some thing to do with it. I also take the medication Spironolactone, not sure if that could possibly affect it either (though I took this last year for a about 6months, and then I began taking it again this year). I just wanted to put this out there to see if anyone might have some insight, but I do plan on talking to a doctor about my meds and etc, either way.
