I am 17 years old and started my period a little more than a year ago. But these past 4 months have been hell. I get my period every 2 weeks or less and they are long, painful, and heavy. I have no idea when I will start my next cycle and my period seems different every time. Like my most recent one is not as painful, less cramps, boys as heavy of a flow, but it's on day 11 and doesn't seem like it'll stop anytime soon. My period are always 7 or more days long now. It's honestly just really annoying now because I'm spending so much money on pads and feel like I'm constantly on my period. What is going on???
