symptoms disappeared

so I am 6 weeks 5 days and I started off with really sore breasts...this isn't the case anymore they aren't sore at all. All my symptoms seem to have calmed down and I've had no morning sickness. I initially had taken about 6 tests in the space of a week all confirming that I am pregnant but can't help but think something is going to go wrong so to calm my nerves I've taken another 2 tonight both positive. My first midwife appointment isn't for another 2 weeks but I'm going out of my mind with worry. Any advice ladies? xx
