8 weeks

I haven't had 1 single symptom. I wouldn't even know I was pregnant if it weren't for my 6 week scan. Is anyone else like this..it can be worrysome. Yesterday I noticed I have a bump right above my pubic hair which I'm assuming is my uterus? Sorry to sound stupid this is actually baby 3 for me but this time I'm overweight so I'm hoping it's normal.
