Hi, am a 22 year old girl who is very active and average wieght. I am on tricyclin low birth control method and have been having very irregular periods. They are not coming late they are come early and not lasting very long. It is more like spotting most of the time and instead of being dark like it use to be it s light and thin. I have pap test regularly and nothing has shown up before. I have had problems with taking my pill on time but nothing to serious expect taking it the next day however the first time i started early it was a week and i discontinued my pill until the following start day of my new cycle. What is wrong with me should a i make an apt as soon as possible or is this just a natural thing that happens to women due to stress and other factors? I cycle has also been more painful cramps and back pain and i know when it is coming even if its two weeks early like it was this time.
