A first she is embarassed because she was professing her love for Romeo and didn't notice that he was actually in the Orchard below and listening to everything she said.
Romeo and Juliet hold conversations in Act I Scene 5, Act II Scene 2, Act II Scene 6 and Act III Scene 5.
Juliet finds out what happened in Act 3 Scene 1.
Capulet's Orchard? No that is Act 2 Scene 2. Act 2 Scene 5 is Romeo and Juliet's wedding and takes place at Friar Lawrence's place.
I suppose you mean Act 2 Scene 5 where Juliet is waiting for the nurse to come back. In Act 4 Scene 5 she is waiting for the potion to wear off so she'll wake up. Act 3 Scene 5 is a busy scene with not much time in it for waiting. In Act 1 Scene 5 Juliet is waiting for Romeo to kiss her when she says, "Saints do not move, but grant for prayers' sake."
Yes she does.
