Dear itsjustme2528-
This could be a hormonal imbalance. The only way to find out is to see your doctor to be tested. The most
commonCommon cold cause of this is a condition called
polycysticPolycystic kidney disease
Polycystic ovary disease ovary syndrome (PCOS). This is very
commonCommon cold - up to 10% of all reproductive age women have PCOS. The diagnosis is made from examination to see the extent of excess hair growth, an ultrasound of the ovaries, and blood tests to look at various hormones including testosterone. If you are overweight, which is pretty common with this condition, then weight loss (does not need to be much, often just 5%-10% does the trick) often helps normalize periods. If weight loss does not work, or you are unable to lose weight, or are not overweight, then you will probably need medication.
Regarding your concern that medication will mess your system up more, this is not the case. The irregular periods are not due to medication, and are neither made worse nor cured by medication. However, many years of irregular periods means that you are not ovulating regularly. When that occurs, your ovaries makes estrogen, but not progesterone. Unopposed estrogen, which is what happens when women do not ovulate, can over time increase the risk of cancer of the uterus, or of suddenly starting to hemorrhage. Therefore, if you are not ovulating regularly and hence are not producing enough progesterone, you need to take medicine that will provide you with progesterone. Which medication to choose depends on your current wishes. For example, if you want to have a baby, you should take a fertility pill, since this will cause you to ovulate. Once you ovulate, your ovaries will make progesterone. On the other hand, if you do not want to be pregnant but want treatment for the acne and hair growth, the birth control pill is a great choice. It has a progesterone in it and so will protect the uterus from cancer. At the same time, since the birth control pill works by shutting off the signal to your ovaries from your brain, the ovaries will stop making testosterone and your acne and rate of hair growth will hopefully improve.
This is a common problem, for which I would recommend seeing your ObGyn or a Reproductive Endocrinologist to help decide which approach is best for you.
PCOS and Hypothyroidism sometimes go hand-in-hand, so your doctor should check thyroid levels and antibodies as well. In my opinion, you should ask your gyn about this, or you could see an endocrinologist as well.
