6 weeks 2 days - Symptoms

Laura • Mum of an amazing 3 year old girl who is my best friend and pregnant with baby no.2 due July 2016!! 🙏🏼🙏🏼🙏🏼
Hi, 
According to my dates I'm around 6 weeks 2 days into my 3rd pregnancy.
My daughter is 4 and then 2 years ago I had a miscarriage at 5-6 weeks.
With my daughter I had all day sickness early on and in a way it was reassuring! This time round my only symptoms are sore breasts, exhausted and mood swings 🙈
Is every pregnancy different?
I'm from the UK so I won't have my first scan until 12 weeks 😬
