Hi Beibei, I am a first time mom too. And I totally understand how you feel. I remember when I was 5 weeks pregnant, I kept asking myself how come I am not getting any pregnancy symptoms except for mild abdominal discomfort. Aside from that, I felt very myself! Don't worry, some women experience more discomforts than others and it is perfectly normal. In about 2 weeks, you may start getting sore breasts... Again, please don't worry about not feeling any signs because each individual is different. Then again, some women may envy you for not going through any discomforts!
