Anyone mommies if twins here ever had a doctor miss twins at ur 6 week or early ultrasound and later found out ur having twins?? I just feel somethings not right. This is my third pregnancy and i feel soooo out of whack. Extreme fatigue,nausea,headaches,showing early,spotting. Also doc says my uterus measures a tad big for 10 weeks. I wont have another ultrasound for another 2 weeks but just curious. Thnx!:)
