I just now to take the pills 5 days after my period but my problem now is? I haven't had a period for almost a year ? And I don't now when I ovulate ? Please help me I'm DESPERATE

That is why you are also not getting pregnant.
And you are 21, why should anyone judge you, what about this do you feel wrong about ? Is there some emotional issues that also need to be addressed.

But no, you need to try to get back to the doctors to address the issue of your periods also ( I will assume you also spoke to doctor about that and he knew ?)

Check & see if you can get medical assistance from the County.. sometimes medical assistance is available to people who need medical help.
You need to get medical attention because you haven't had a period for over a year - this is a good reason to need help.
Here is a site that may help you about ovalation

I know a girl who did not have a period due to her weight -- she lost a LOT of weight, and it straightened out -- however, that may not work for everyone.
Check and see if you qualify for Medicaide - and ask around who might give medical assistance.. call the Attorney General's office of your State (or email them)and ask where you might get medical attention.
