HELP. PLEASE. COMMENT.

Please comment and help me. Need to ease my mind.
I am on microgestin, the combo pill. I have been on it for over a year and have maybe missed about 3-4 pills ever. Since going on it, it made my periods very very light, and my periods were already pretty light so it made them SUPER light and to the point where they wouldn't even come some months. When I do get my "period" it's just a little bit of brown discharge. That's it. Every time I miss my period, I take a pregnancy test and it's negative.
I missed my period two months ago, and last month. I took 4 tests of the course of those months and they were all negative. I went to planned parenthood, and negative. I feel totally fine too! I don't feel off or weird or have any pregnancy symptoms besides my normal PMS ones that occur even when I miss my physical period. On top of this- I also rupture multiple ovarian cysts a week. Yet a doctor denied that I have PCOS.. which i quite frankly don't believe that I don't have it. On NYE I have the most AWFUL cyst pop, (to the point of almost going to the ER) and I heard these cysts make your period late or not come. So starting on Sunday, it'll be my period week and I am feeling normal PMS symptoms, that's all. Y'all agree I'm not pregnant right? I mean I took multiple tests. Has anybody else had something like this before? My body is so weird!!! Thanks so much.
