Sore breasts and light cramps

Jocasta

I'm 6 weeks 3 days, so far I haven't really felt sick, the only really noticeable sign of pregnancy is sore breast and intermittent cramping, like period pain, in waves throughout the day... do you think everything is ok? I'm worried there aren't enough signs to believe the baby is growing, or am I being impatient? First dr app will be on 12th Sept, in the UK. Any advice would be amazing...
