Symptoms?

Mommy
Hey ladies I'm 4 weeks and 5 days. I'm bloated and a little tired and watchu appetite but no morning sickness per se. All in all I'm feeling pretty good. After reading a bunch of posts it now has me thinking....should I be having more symptoms this soon?? I've never miscarried and have 2 much older children. I remember nausea and extreme fatigue with them but maybe it was further along. My doctor doesn't want to see me until 8.5 weeks. When did your symptoms really hit, undeniably?
