This is my second pregnancy and other than some weight gain and a growing belly I have, for the second time, no other symptoms whatsoever - so it can and does happen. No tiredness, M/S, food aversions or cravings, sore boobs, nothing. Everythings fine though I just don't get the usual pregnancy symptoms and you may not either. It makes it hard to believe all is well and the pregnancy is real. I still forget I am pregnant and am often wondering - "was I supposed to eat/do that" as it doesn't occur to me that I'm carrying a baby. You will feel more excited, I think, when you feel the baby move (a long way away I know) and for now, you should feel happy about having no nasty symptoms (yet!). All sounds normal to me. Big to you.
