I have been spoting off and on all month long.. my periods have been a lot longer than usually and I don't thnk I have had a period since feb 18, 2012 and u tell me what could be wrong?

Can you give us some more information? How old are you? Are you on birth control? Were you on birth control but no longer are? Have you hat protected or unprotected sex recently? Have you been or do you see a gynecologist regularly? All of this information will determine what answers we can provide.

Also, do you mean that your last period was 2/18 or that your period was due 2/18?
