Everybody reacts to pregnancy differently and no 2 pregnancies are the same so it's a bit difficult to say what will or will not happen to you.
You may get stretch marks, so moisturising is a good idea
When you get bigger you may want to invest in a pregnancy pillow for comfort
You will more than likely cry over stupid things that you wouldn't normally
You should expect to feel movements soon, once you do see if you can work out a pattern
Make sure you have plenty of iron in your food
Expect people to make comments on your bump ... Strangers included
People will want to touch your bump too ... Even without asking
Any concerns you have, make sure you contact your midwife
Other than that go with the flow and enjoy pregnancy
Oh also after 20 weeks you will get your matb1 form, your other half will need a copy of it for his paternity leave ... Most companies require it.
Mainly, just relax, but like I said every pregnancy is different so there is not set way for it to go really x
