@kate3150 sorry to hear about your earlier loss, that must be very difficult and would naturally make you more anxious about this pregnancy. Wishing you health and happiness for the remainder of your pregnancy!
@smarrtcarnotsosmartdriver what a predicament re work, I feel for you. Sounds like it's going to be a rough few months but it will all be worth it when your wee one arrives 
Seems like mental health is a factor for most when pregnant so not all happy, happy, joy, joy as folk on Facebook would you have believe (which I knew anyway really). Can I ask, when you say that you are worrying/anxious, what are your main concerns? Is it the viability of the pregnancy, the health of your baby, your own health, how you'll manage when baby arrives?
As selfish as it sounds (baring in mind that I am not yet pregnant), my main concern is for myself. Will I cope mentally, will I become physically ill with something 'unfixable', might I die, etc. Sounds extreme, I know, but I can't help but worry about these thing as my anxiety is very much health related. FYI - I have no health issues at present.
However, I am 34 (35 in October) and have PCOS so I'm a little concerned how these factors may impact a pregnancy. I know there is loads of info out there (I've read a lot of it) but as every pregnancy/woman is different, it's the not knowing that I hate.
Anyway, I'm rambling now! Thanks again to all of you for your replies, you have been really helpful x
