I am 19 and I have really irregular periods. I usually don t miss one for more than 3 months, and sometimes they are perfectly regular for 3 months or more. They used to go every other one was heavier than the last but i haven t had one in about 3-4 months, just light spotting last week. This is starting to worry me and i have recently been looking into PCOS and the thought of having it actually terrifies me. I have excess hair on my chin and upper lip but i come from a family of dark hair. The upper lip hair is usual but it bothers me more on my chin. I am also quite over weight. Im about 190lbs and only 5 4 but I am not a healthy person and i haven t been for years. i would eat way more junk food in a day than anyone should eat in a month, I m surprised i don t weigh more. Im also a freshman in college so before starting i was around 170. Its only been recently that i have cut out junk food and I m working on getting more excersise. I don t have a OBGYN or any type of woman s doctor as I m still on my families insurance and seeing the family pediatrician. I have been tested for thyroid problems and anemia after a series of illnesses and when i was a sophomore in high school my uterus was looked at for cysts and i had none. i don t know if this makes any differences but i am allergic to all nuts, bananas, seeds, and shellfish. My sister is Diabetic. I just want to know what i should do and if my irregular periods could be caused by my bad health, lack of exercise and stress as i am in a stressful major. I also take Vyvance a medication for ADD. Im interested in anything you have to say and thank you for taking the time to look at this.
