Hi I'm 15 and my periods have been all over the place since I started them when I was 13, has anyone else had periods that stop for about 6 months then come back very Heavey with cramping and server pain for about 3 periods, this month they have been very heavy with pain and cramping and have lasted 18 days and I still have them 😔 I have seen the Dr and because I'm still young he thinks it's just my body going crazy. I would like to find out if anyone has had the same irregular periods?
