Congratulations! It is perfectly normal to feel that way. I'm pregnant with my 2nd, and had a hard time believing I was really pregnant this time too - after 3 pregnancy tests, and a blood test! But seeing the little critter squirming around on the ultrasound put my mind to rest. I found that the wait for the ultrasound was the longest 3 weeks ever, so can understand. All I can say is take each day as it comes, and enjoy your pregnancy. Xxx
