No early pregnant symptoms what about you?

Emma • Baby #1 - Boy 💙 born 14 July 2015!!
Ok so all my hpt's are showing bfp but (other than a bad headache now and again and feeling tired) I have no symptoms. I've worked out that I'm 4 weeks and 4 days pregnant but have no nausea, slightly sore boobs, no darker nipples, nothing to what I thought I would feel when pregnant. Is this normal? Has anyone else experienced pregnancy this early on with no symptoms? The midwife won't see me until 1st Dec so just a waiting game until then. Your advise or comments are appreciated please x
