Thanks for the reply @amiracle4me much appreciated!
I thought as much, just didn't know if I went at midday if it would possibly be ok. My clinic opens at 7am, but I'm unsure if I'll be able to just go in at 7am tomorrow without speaking to the nurses first.
I had expected to need to go in most days for scans and bloods, I just wasn't expecting AF to show now! I almost rang the clinic on Friday to ask "what if" this happened, but thought I'd be wasting their time.
Thanks for the reply and for the luck.
Good luck to you as well! I look forward to getting to know you!
