Did you have a miscarriage if you have been on ortho tricyclen low for three years and your period came a week early and was a pink tissue discharge and now it is very dark?

Hello, No this isn't caused by a miscarriage hun. But it does sound like this may be bleeding related to early pregnancy (implantation bleeding) or the effect of birth control. Sometimes when someone has been taking birth control consecutively for a long period of time, their period cycle can change or become lighter or more irregular or sometimes, your body becomes so reliant on the doseage of birth control that you need to doseage changed (usually increased). See your doctor for a pregnancy blood test.
