Since you've recently come off the pill, it could just be symptoms of that rather than pregnancy. It can take a little while for your body to adjust to not being on the pill anymore therefore taking a little longer to conceive than you would like.
If you get your first 'normal' period after you stop the pill then it means you are ovualting again and if you don't, don't worry about it you will ovulate again soon. Some woman find they get their periods straight away others find that they have to wait a couple of months.
Since you're close to getting your period, I would wait and see if that arrives, if not wait 7 days and then take a test. Then wait another 7 days and retake the test to confirm the results.
I came off the pill feb 09 and got pregnant within 5-6 months but I lost that pregnancy. Most couples who come off the pill get pregnant within 6 to 12 months.
