I'm way behind, so apologies to anyone I have overlooked here, ''tis not intentional!
Mimi I'm sorry you've been feeling low. It's all so rubbish at times, it really is hard. Hope you're feeling much better now 
Daddysgirl Same to you, sounds like a v rough time, I do hope you are feeling less upset and stressed about everything. It's so understandable, you're not alone and it sounds like you've reached out for support which is a really brave and positive things to do. I hope you are able to see the IVF referral as a positive too, though I know it may take time to get your head around it. I'm not at that stage just yet but I know it will be a challenge for me too if we end up there. However, the last 18 months has certainly taught me how the way I feel about things can change and with a bit of time I've been able to deal with things pretty ok when they initially felt terrifying.
Chlo - Sorry that AF taunted you soooo much and then got you, that must have been so hard. Hope you're feeling a bit calmer now the stupid hormones have hopefully eased off. Great news that your appointment at the Lister went so well, thanks for sharing and I'm glad you have what sounds like an encouraging plan there.
Elleybear I don't know whether you're still here or have hopped to a secondary board, but if you are here then I can see your point about finding out something that you aren't able to fix. But there's always the chance that there is an easy fix, so personally I'd at least get some basic bloods done just to check that you're ovulating etc. If you are then that's great, but if you aren't then no amount of trying is going to get you pregnant, and there are meds that can help with that. Good luck!
Cola Great stuff on getting the swimmers up there, big tick in that box and the waiting game is here again! Hope your appointment has gone well.
Sunshine - well done on your FW action too. Must be something in the air cos we had a good one this time too. Twice in one night and no need for me to nag at all, which is an actual miracle. I'm sure that won't happen again!
Bertie I'm so with you on the contraception thing. A friend of mine had a coil fitted recently, which apparently isn't a barrel of laughs (who'd be a woman eh?) and I had a bit of a laugh with her about the comedy of us comparing notes on having someone mess with ones cervix for entirely opposite reasons. I feel like I want a refund from Durex after many years of purchasing products that it seems I didn't need - can I claim back like PPI?! 
We have our consultant appt on Tues to talk through all results (bloods, HSG, ultrasound, repeat SA) so am feeling a bit apprehensive. I've got it in my head that because I appeared to have a blocked tube on HSG they will want to do a lap, which terrifies me due to my silly squeamishness and terror of hospitals, needles etc. Need to chill and not pre-empt the outcome I think. One step at a time and all that. I will also be 10dpo at the time of the appointment which is usually when my hormones really kick in and turn me into an over-emotional wreck at the slightest provocation, so I'm def taking some tissues with me!
Good luck to all tww-ers, I'm with you
