I had a misscarge about 5 yrs ago. I never got myself looked and cleaned out by a doctor; can I still become pregnant?? PLEASE HELP ME...

Your body likely took care of things itself... however, have you had regular doctor visits since that time for pap smears and such? If not, make an appointment to be seen so that you can discuss things with your doctor and ease your mind.
Most women have a miscarraige at some point in their lives, they just don't always know it, and most will go onto have healthy pregnancies afterwards.
