Basra,
A lots of people that I came across that did the same mistake you did either never took the time stop and ask the same question which you did or didn’t cared enough, so, let me first applaud you for asking.
As for you question, the Prophet (peace and blessings be upon him) is reported to have said, "If somebody eats or drinks forgetfully, then he should complete his fast, for what he has eaten or drunk has given to him by Allah" (Al-Bukhari and Muslim).
In other word, your fast is not broken as long as you did not consume anything after recognizing that you are supposed to be fasting.
Ramadan Kareem
