I would suggest seeing your OB/GYN. I had this problem, and went to several primary care physicians who did nothing for me. I finally went to a gynecologist and was diagnosed with polycystic ovarian syndrome.
You should definitely see a doctor about this, as it can have adverse affects on your health, including infertility and an increased risk for type 2 diabetes and heart disease. I know talking about these things with your doctor is unpleasant, but it really is worth it in your case.
It is perfectly normal to have abnormal periods at any age of your life. I think if you are that concerned you need to see your GYN to discuss your concerns. Blood work could give your doctor a clue with what is going on =)
okay, how long can have abnormal periods?
thanks for the info. i need to call my doctor and ask him about this. because, the last one i had was in oct of last year and then now in april of this year. that's been four months later. i will call my doctor to ask what's going on.
