Hey Trueblue ~ Hope you've rung the clinic and they have eased your mind. As Juniper said and also my friends a lot of people get spotting and everyone is different too. So I wouldnt be too worried.
Yes the Synarel was cheaper from chemist warehouse. Can't remember how much because Sam picked it up for me but I remember him saying it was cheaper.
Thinking of you hun and FX all goes to plan, GL xoxo
