Ever since I got my period when I was ten, I’ve been really regular. Every month it comes when it should and it always last 5-6 days. However for the past three months my period has been late by 4-5 days, and this month it came a whole week and a half early so my cycle was only 21 days long. During these periods my cramps have also gotten even worse than they were before and my right ovary (?) has been hurting a lot too (I was also told I have 2 cysts on it). Is it weird that this is happening? I’m also a teenager on the slightly older end.
