Hi, I'm 21 this year. I need help. My menses came 1 week earlier, it started off with mild bleeding for the first 3 days, and the 4th it came as per normal and lasted me in total of 13 days period. 

after 2 weeks, i had abnormal bleeding and it lasted me 1 week. Same thing happened again 2 weeks later, and right now, as of today, it is the 4th time happening, each time, the abnormal bleeding gets heavier.


what happened to me?
