Rabbit - so sorry you have unwanted butterflies. You are very self aware and although this is horrible at the moment - this too will pass. The yoga interest is really great so give yourself a pat on the back. I think what Pout said about ensuring you keep to a routine during bad times is really good advice - am taking that on board myself so thank you Pout.
Rabbit - I know what you mean about that horrid butterfly / gnorring feeling that just won't go away. Could you try writing down on paper any random thoughts and feelings - not in a constructed way, just go with the flow. Get it all down - it will really give you some release. Then take a deep breath and go for a walk, or have a glass of wine but do something nice. Big hugs -it's not suprising that the horrors of TTC have keft you feeling wobbly. Also remember, from here on, the only way is up!!! Please remember that you have every chance of conceiving in the next few months. Take care of yourself.
Thank you everyone for the wise words about the pregnancy tests. It is good that my tubes were clear last week and this gave me a really big boost - but unfortunatly there are no guarentees they they will stay that way. I can't help feeling my maya massage and caster oil pack have contributed towards clearing them so will be keeping this up.
Just got back from the clinic - so so so so cross!!!! We only went to sign some papers for upcoming FET. When I was there I asked the nurse to clarify the day I would expect to have a 5 day embryo transfered. I don't know if you remember me saying but the nurse last week was adament that the blastocysts should be transfered on the day of ovulation. This was despite me commenting that this was unusual and asking for clarification and checking again with her twice more during the consultation. But no - apparantly I was wrong "the blastocyst needs time to adjust to the new environment and you need to be available for transfer the day after the LH surge". I found this very odd as the endometrium is only thick enough and chemically ready later in the luteal phase, so I thought. I even rang the Dr's last week to clarify - they didn't know for sure either but seemed to think that transfering on ovulation day would be ok. They said they would check it out and get back to me - but they never did.
So today, I learn that "embryos are transfered how every many days after ovulation, as they are old" i.e. 5 dpo. Which is what I always thought. I am not cross that someone made an error and possibly confused me with an IUI or natural IVF patient. I am cross because when I challenged the first infomation, there was no attempt to double check or explain the theory - therefore I find this arrogant. I am also cross that staff seem to back each other up. If I had followed the original advice, my blastocyst would have died instantly due to being placed in a hostile environment.
Then, following on from some of the conversations here recently, I decided to open up conversation about immunes. Can you tell I was really in the mood for it??? 
I asked for a blood test there and then to test my HCG to see if 'something is trying to implant'. I was given the usual jabba about using pregnancy tests instead etc. Then I said, "but some months I think I can feel things happening but it just comes to nothing". I asked the nurse what she thinks fluttering in the womb from 8 - 12 dpo might be? She said it's likely my period coming as I am 13 dpo today so nearly time. I pointed out that these flutterings have occured since 8 DPO, so not near period time?
She said that 'as someone who has been pregnant before she didn't think it was definatly a sign'. I told her 'I too had been pregnant before and that I have also had a miscarriage before and that I have also had IVF before and as a result I feel I have a wealth of experinces that need listening to. 
I said 'I wonder if I have some sort of autoimmune disease as I have regular (almost monthly) mouth ulcers and facial tingling which usually occur around period time'. The nurse ran off to check with the Dr to see if I can have a blood HCG pregnancy test based on my 'immunology weak implantation' theory. The Dr said no - I would "need a positive pregnancy test and bleeding first" before they would check this out. In my opinion, today was the perfect chance to check - 13 dpo with funny flutters all week.
At the point I was telling the nurse all of the above, the flutters started up again - I kid you not. .
The Dr who said "no" to my pregnancy test request was the same Dr who said I may be in ovarian decline back in May! He then said (via the nurse) that if I wanted to discuss immune issues then I could but need to go and see the consultant. Now this is not a bad idea and one I will persue as I have a nice new consultant. BUT - when I was first referred to this clinic and saw the other consultant (awful one) I did try and bring up immue issues and I was poo pood immediatly!! So now I'm cross that this door was closed to me when my clinic will look in to it - usually after failed IVF cycles. But my point is, it's not just the failed IVF cycles, what about the 'unseen' failed natural cycles????
The upshot is - I am going to proceed with natural cycle FET as planned in September - but on the correct day for transfer at least. I am going to follow this up with a request for immune tests if I get no success.
Despite all of my ranting above, I was very calm and polite to this nurse. It wasn't even intended to be that type of appointment.
What have I learnt? Unfortunatly many of these people are perhaps not the experts we thought- they are faciliatators and often don't have higher level knowledge of the different scinces or peoples emotions.
Ladies - question everything!!! If it doesn't sound right - it probably isn't! Trust your instincs in addition to being guided by the Dr's and nurses.
Good grief - what a rant - sorry ladies! I guess I am fed up with being a 'victim'. I just want a baby.
