Those copper T's can be very dangerous. They don't actually keep the egg from becoming fertilized, they just cause you to abort it when it tries to implant in the uterus. If you have an especially determined baby, they can implant in spite of the T and then the T can cause birth defects. The T can also puncture the uterus causing all kinds of bleeding and problems. I would highly recommend getting your hands on a book entitled "Taking Charge of Your Fertility". They say that people who use the 'rhythm method' are called 'parents', but this book takes you far beyond this method and teaches you to understand your body and the cycles it goes through each month. I often recommend it to people you are trying to get pregnant, along with those who are trying to avoid it.
These cysts on your ovaries are not uncommon for someone of your age. They often are associated with hormonal imbalances and poor diet. I would recommend using the female formula, hormone formula, wheatgerm oil and then, taking a good look at your diet - in other words, how much processed foods are you eating? How much meat and dairy? The above mentioned formulas will help to cleanse and rebuild these organs so that they can function properly.
