Yes!!! And enough wind to propel a cruise ship as my husband delicately put it the other day 
HCG and you increased progesterone right now will also give you teenage skin and all sorts - your body is essentially completely rearranging its priorities and gearing up it’s hormones to do a completely different job than the one it’s been happily plodding along with for your whole adult life. The only other time it’s had to change this much was puberty, when it had to go from just keeping you alive to getting your body ready to potentially have a child, and it had a couple of years to do that.
With pregnancy your body has to completely flip its focus in weeks, not years and so pretty much every hormone (including things like insulin weirdly enough!) gets impacted as everything rebalances.
There used to be a school of thought in the early 1900’s that the frequent bowel activity and vomiting in early pregnancy was the baby cleansing a woman’s body ready to keep a pregnancy healthy, women who were particularly sick were often told it was their own fault for eating unhealthily before the pregnancy. It was seen as a real sign of healthy living if you fell pregnant and got no sickness. In the 1700’s however, if you had no sickness or bowel related symptoms at all then it was a sign you
might not actually be pregnant - often diagnosis of a pregnancy required an absence of bleeding AND for the woman to have been observed vomiting or other digestive symptoms (because of course she couldn’t be trusted to just tell doctors she was feeling unwell). This meant that most pregnancies weren’t confirmed until ‘the quickening’, when a bump started showing, because so many women don’t actually experience symptoms at all in early pregnancy.
My point being, anything and everything you experience at the moment is probably pregnancy related, and there’s no ‘normal’, just normal for you!
The only things that should be a worry are bright red bleeding and cramping, or sharp pain experience don one side.
