So I'm 15, I've had my period for 5 years now. It's always been irregular, but now I'm not sure if I should start to worry, because I've been having a lot of symptoms. I'm not sexually active (the closest I've ever gotten is my boyfriend's finger that didn't even go all the way in) but I've been having cramps, spotting (its been on and off for about a week or 2), and really bad gas. I'm not sure if this is important, but my mom had irregular periods until she went on birth control in her mid-twenties. A few years ago, I went to a doctor and had an ultrasound done of my uterus and everything was fine, but I read that your cycle is supposed to regulate itself within a few years, but it's been 5. Haha, I really said all that to say, does anyone know what could be going on? My period last came in March, and it's definitely not pregnancy. In fact, my gas started when I started taking Vitamin C to help my period come faster a few weeks ago! Could that be delaying it? Normally it shows up every 3 months or so, but I'm still waiting.
