Hello to everyone 
Really great to see everyone's stories and find other people going through the same thing. Pleased everyone is really positive and wish you all the best of luck... hang in there!
I have been ttc #1 for 9 months.... Came off the pill in September, felt horrendous, no periods for 3 months, all the tests, find out I have PCOS (I'm 28 but had been on the pill for ~10 years). Now have established a long ~38 day cycle but with late ovulation and a short luteal phase. I also have the 'lean' type PCOS, with all normal blood tests so far, if people are interested in that type of thing.
I'm still feeling positive but have to admit it has been a real emotional rollercoaster so far... so doesn't help that hormones are all over the place!! My two best friends are both pregnant, one due in 4 weeks and one due in October. Both got pregnant straight away. I'm truly happy for them, but struggling a bit to be honest.
Anyway, DP is off to JIAC (jizz in a cup) tomorrow, I'm going to have another round of blood tests this month, then our GP is going to refer us to a specialist and hopefully we can start Clomid later this year. We're getting married and going on a long holiday in August/September, so probably after then, giving us time to sort out our lifestyles before then.
Things we're trying:
Low sugar/GI diet
No caffeine
No alcohol
Regular sex all month long 
Exercise - DP is already superfit, I've just joined a gym
Meditation - going to our first class next week!
Yoga - also to strengthen my body for inevitable pregnancy (!!)
Masses of vitamins - Iron, Magnesium, Selenium, Zinc, all the Bs, plenty of E and C...
I got all these lifestyle tips from a really good book I have on my kindle - unfortunately I don't have it with me today but I will post the link when I get chance.
Regarding agnus castus, I bought some then was too scared to take it, since I also read that it can mess things up more. I will check out the links posted by LittleMissSnowShine though.
PS, congrats Hetty Great news!!
