Nervous - symptoms fading

Today I’m supposed to be exactly 8 weeks, going for my ultrasound on Tuesday! I’m ridiculously nervous of the outcome. My 4,5, and 6 week of pregnancy my boobs hurt so bad. However, in week 7 they are much much less tender. I’ve been nauseous almost all the time but after reading how prenatal vitamins mess with some women’s stomachs I’m worried it’s not real morning sickness. I’ve been tired and have had strong food aversions though. My favorite foods taste disgusting. Still pretty emotional. No cramping besides some hip pain that i think is normal, and no spotting since some light pink/brown my 4th week. Has anyone had symptoms like this?
