Bumpdate

Emily

So I'm 20 weeks and 5 days but I've gained only about 5 pounds and have been really sick my whole pregnancy, I have my anotamy scan in 4 days and I'm worried that baby isn't big enough, am I just worrying myself too much or is this all normal? Anyone else not have much of a bump yet at 20 weeks? Everyone says that I don't look pregnant but I feel pregnant for sure. I could really use some insight here ladies.
