My last ultrasound was at the end of April and I was I believe 18 weeks at the time. Next Friday when I am 28 weeks I finally have another ultrasound. It took my doctor quite sometime to see if it was a boy or girl due to the baby being stubborn. He said he is definitely sure it's a girl due to the "hamburger" theory. I'm skeptical just because I always look toward the bad and I'm a worrier. Especially since everyone keeps buying girl items and I'm mostly done buying. I trust him because he has delivered many family members of mine and friends children but like I said I worry. Opinions?
