If you've had no period in 4 years you need to make an appointment with your OB/GYN and .get a referal to a fertility specialist (or skip straight to the fertility specialist if you have that option). You may be able to get pregnant with help, but they will have to run some tests to determine where the problem lies. I know missing your period for that long is very discouraging when it comes to trying to conceive, but it doesn't necessarily mean you can't get pregnant. I was in a similar position, and now I have twins (yes, I did have to take fertility drugs to ovulate). GL!
