Subsided symptoms

So I am 6 weeks exactly and I woke up this morning with no breast pain anymore, no sore nipples, nothing. I haven't been sick in 4 days and I have felt fine besides heartburn yesterday. Should I be worried that my symptoms seem to be subsiding?? I go to doctor in 5 days for US and I'm trying to be so patient and not worry until then but I'm tempted to buy tests to see if it's my hcg but dont wanna do that to myself. Someone tell me I'm crazy and it's ok not to feel symptoms some days 😔😩
