I've been trying with my boyfriend for four years and nothing. My new boyfriend I have been trying for 9 months and also nothing. I don't understand why it isn't happeninig and maybe you can help me find out why?

See your doctor for a check up. Also maybe its just that your not married.

But I am not married and still young,not that young, but young so I don't understand why I can't

See a doctor. OBGYN and get checked out. It could just be something simple your not picking up on.

Miichelle18, we cannot diagnose you over the internet. There will be tests that need to be run, specifically blood tests and ultrasounds and we cannot do that here. ONLY your doctor can do that.

You will need to see your doctor for a complete health work up to find out why you are not getting pregnant.
