Surging hormones

I've started and then deleted a number of posts over the last week and I'm putting it all down to hormones making me alittle crazy.  I'm in a natural cycle without all the drugs I'm usually on, but for some reason I am coping worse this cycle than ever before.  My anxiety has been through the roof over the last 24 hours to the point where I feel like I'm already grieving a BFN and we haven't even gotten to transfer yet.  I've been freaking out about my surge being delayed, angry that I feel like I'm floating along in this cycle on my own without any FS running the show and this morning I pretty much burst into tears because the nurse couldn't answer my question about what drugs I needed to pick up for luteal phase support.  Thankfully my bloods from this morning confirmed a surge and I've managed to pull myself together enough to realise it's the rising hormones that's got me over-reacting about literally everything.  I seriously don't ever recall being this emotional around ovulation.  I'm fed up with my clinic, my FS and all my repeated failures at this IVF crap.  I'm also angry with myself for not demanding more from these people and putting up with such little progress in treatment to date.  I was  so traumatised by that last BFN.  It took me a long time to even think about doing IVF again without crying and now I feel like I'm experiencing some kind of Pavlovian response from being in a cycle again.  Essentially I'm a bit of a basket case at the moment ... but apparently I'm good to go for a transfer this Thursday.  AND shock horror, my FS is actually requesting more bloods post transfer to monitor my progesterone levels this time.  I am praying for her to give me something ... ANYTHING different to do to get through this cycle.
