Pregnant with little to no symptoms

I got my BFP on Feb 28th and got a qualitative blood test done to confirm. I must be 5-6 weeks now. I have mild cramping and leg ache now and then. I don’t have any other symptoms that members in the app mention. If not for the test i could never tell i am pregnant. Is this normal? This is my first pregnancy and my doc appt is not until couple of weeks. I am very confused.
