GM - we are a lovely bunch (even if i do say so myself), and you will always get support and advice whatever your question (and however stupid it is).
if you read back through the thread, you will find we talk about all topics, including boobs, sex, poo-ing, peeing and even, occasionally, running.
have you been to the GP yet? you should get a booking in appointment with a midwife and, possibly - depending on the policy in your area - a 12 week dating scan. (not every area does those though).
also - not sure how much research you have done yet or how old you are, but if you are worried about the risk of downs and other chromosomal disorders, you can get a scan done at about 11weeks (i think they can do it up to 14 weeks, but in my area they prefer to do it as close as poss to 11) called the nuchal translucency scan. in my area you have to pay for this (it costs about 140 quid for the scan and the blood test), and it gives you a risk factor for having a baby with downs or 2 other disorders by looking at the amount of fluid at the back of the baby's neck, and also by looking at the level of certain hormones in your blood.
you will be offered a blood test for downs etc on the NHS at about 16 weeks or so, and lots of people just opt for that, but it's generally thought to be quite unreliable and give lots of false positives, and several of my friends have had high risk readings from these blood tests and have ended up having to have an amniocentesis (which carries a 1% risk of miscarriage). in all cases, the result was negative, but there was a whole lot of stress and worry and waiting involved to find out. with the nuchal scan, they give you a rating there and then, and confirm it more accurately when the bloods come back about a week later. and it's much earlier in pregnancy (ie 11 weeks rather than 16-17 or so for the NHS tests).
it's probably a bit much to think about at this stage (and you will be overwhelmed with everything else if you have only just found out you are pregnant!), but if you DO think you will worry about the risk of downs, i would heartily recommend the nuchal scan if you can afford it... your midwife should be able to tell you if/where you can have it down, and in some areas it's offered routinely on the NHS (although not in mine).
