Lack of Symptoms. Help?!

I am 5w3d and am currently not having hardly any symptoms. I was experiencing exhaustion, super tender breast, some morning sickness. For the past couple days my breast haven't really hurt. I haven't felt nauseous and I'm struggling with sleeping. I continue being extra sensitive, hungry, and I have to pee a ton but I feel like all of those can be caused by other things. Should I be worried or thankful???
