Bearish for GBP/USD?

Bearish Trend Start From Here?

After have followed GBP/USD for 10 hours, atleast I see 1 and half big bearish candle stick, does it mean Up trending already over? For my prediction is the bearish trend will start from here, If you want to Sell, wait for a little longer for another bearish Candle Stick for confirmation.

Keep in mind, it better if you have another hard fact news to confirm this
