I don't know if there is something wrong wit me or what I been having all these problems I cnt go to the doctor I have no insurance any more..

Have you tried a pregnancy test? Check out a planned parenthood, the health department, or a pregnancy crisis center and you can likely get a free, or for a minimal fee, test done.
If you had recent sex, some women will have a bit of spotting or light bleeding for a couple of days afterwards.
Had you been on any sort of birth control before the unprotected sex? Some forms can throw your period off once in awhile.
Do you qualify for Medicaid? Might be something to look into so that you have some coverage.
There are a number of possible reasons for a period to be off. It will be worth the peace of mind to get things checked out.
