You need to see your gynecologist. Your periods should be more regular, especially when you say it was just starting in February that your periods started coming every three months. That combined with the long periods suggests some blood work needs to be done. It could be any number of things, many of which are an easy enough fix once you know what's going on.
Do you get pain with your periods? Is the flow heavy? Is there blood clots?
I don't really have any pain. And its not heavy but light its like moderate. What would a blood clot look like? And I don't even have gyno. I don't know if my insurance covers it or not.
Are you under a lot of stress? Underweight ? Athletic? Sometimes these three things can effect your cycle like that
I'm sometimes under a lot of stress
I forgot to ask your age how old are you?
