Pregnancy symptoms

So I am 4 weeks pregnant with my second and am wondering when did you feel pregnancy symptoms? I remember having cramps with my first, first. Then shorty after I had an aversion to red pasta sauce and wanted to barf anytime I thought of red sauce, that was like 4 1/2 weeks. Then I felt tired alllll of the time at around 5-6 weeks. Just curious when I’m going to feel pregnant! I know I might not even have symptoms.
