Morning everyone 
Pickle - You are going to have to put yourself first. There's no way you can plan your IUI six weeks in advance. It won't work and the stress of wondering whether your ovaries will comply with your schedule would be awful! Presumably your clinics don't last all day? So you should be able to nip off for your IUI at some point in the day? If not, you will just have to call in sick if that is the only option.
Caution - Definitely book your consultation for sooner rather than later. I had intended to start IUIs in January but at my consultation in December the clinic requested things which ended up pushing my first attempt back to February. You may as well get going asap, then if anything crops up you can sort it out without feeling that its delaying things.
On supplements, I like the Wild Nutrition Fertility pills. They are crazy expensive but each nutrient is in its natural form which means your body can absorb and metabolise it, whereas a lot of the cheaper supplements are synthetic versions and have all sorts of funny ingredients in the binding. I tried Pregnacare and SevenSeas both of which gave me an upset stomach. The Wild Nutrition ones have given me no side effects whatsoever, but they're £30 a bottle which only lasts one month.
Having said that, the only supplements that are really important are folate and vitamin D.
Your diet is the best place to start. Same as Kwick said, with the addition of a good variety of other fish and vegetables, eggs and full fat dairy.
Kwick - Glad you had a lovely time in Mallorca . Really pleased you've sorted a GP appointment. Definitely mention your foot as well. Are you flat footed? If you are, just sticking some arch support insoles into your shoes can make the world of difference. If it could be plantar fasciitis, rolling your foot over a tennis ball can help to loosen it up.
Stork - You're sounding very positive . Glad everything is going well and that you're coping with the injections. I've managed to learn to inject my heparin without bruising now. Still hurts like hell sometimes though!
Karen - Sorry that things have been a bit of a hassle. Remember that is just admin really and has no bearing on the success of your next attempt. As others have pointed out, given the stress at my last IUI appointment and me feeling so negative about it, it just goes to show that our mental state doesn't really play much of a part in it so just go with it and see what happens.
I have my 12-week scan next week. It can't come soon enough! I've had period pain like aching the past couple of days which has unnerved me a bit.
