Help please!

Ladies,
I'm so confused!!!! I used an ovulation test on Nov 7th and I got a positive, but all the ovulation calculators I have tried say my ovulation day should be around Nov 11th. I did just come off birth control after being on it for 6 months. Could that have made me ovulte earlier than what Glow predicts? My huaband and I have done the baby dance every day aince AF ended and plan on it up until the 14th. Do you think this work and should I have a good chance of conceiving? Help!
