Second round with frozen

Natarsha • Been trying for baby #1 since June 2014 .. I have a blocked right side. IVF started April 2016
Morning ladies I'm new to this and wondering how different round 2 is from the first since we aren't waiting for any eggs . 
I start my period any day now (cycle day 30 on 12th July).
I have the specialist booked in for the 28th July. 
I should be ovulating around then.
Then I'm away for exams and prac from the 30 July -6th August ... When do you think they will insert frozen? Would I have to wait for my August bleed 😩
