Hello New you sound very pregnant. I had every single one of those symptoms. You will get all sorts of funny aches and cramps and muscle twinges as your body adjusts and expands.
As PPs have said, your nausea will not be the same as the next person's . What's worked for me: fizzy water, drinking through a straw, ginger biscuits, dry biscuits/crackers, toast, carbs carbs and more carbs, root ginger, ice lollies (especially lemonade), sour fruits like fresh raspberries, sucking on ice cubes. My biggest nausea cure is just to lie down and rest.
Boob-Ache: it's a killer isn't it? My boobs have expanded massively so at 14w I'm already on my second pregnancy bra. I've also stopped wearing underwires as they hurt the sides of my boobs.
tiredness: it's really wiped me out most days. You do need to sleep more and rest more. I find even a lie down with no sleep sometimes helps. I'm having to sit down more too. Sometimes I've been so tired I've gone to bed with all my clothes on!
Stress: being pregnant has really changed my priorities. I've done a lot less work but don't think anyone noticed (note to self for future!), I told a friend I could trust at work and she's covered for me a couple of times when I really needed to duck out of something. Most of all I've put a mental distance between myself and all the work stress, and I've put my health first. Hard to do sometimes, but I've got added incentive now. If it gets really bad you could consider telling your boss early, but you probably don't want to just yet. Be aware that pregnancy hormones can make you extra anxious and worried - forewarned is forearmed.
Work: when you do tell work, they will need to do a risk assessment on you and then either take risky tasks (handling dangerous substances, climbing ladders, working really long hours, carry heavy things) away from you or, if they can't adapt your job, they have to suspend you on full pay. They have a duty to make sure your job doesn't impact on your health or the baby, including stress.
midwife: yes, you have your booking in appt about 10 weeks but that is mostly a form-filling exercise. It depends where you are as to how much your mw will answer questions (mine was fab). I've also started going to an aquanatal class which is run by a private mw and there's a tea and biscuits session afterwards which is great for asking all those questions. I've also joined an ante-natal thread on here for the month I'm due and that has been fab.
Oops that's an essay, sorry!
But most of all, many many congratulations
I hope you have a lovely and uncomplicated pregnancy (without too much vomit)
