Has anyone had their first ultrasound? I'm due around the 12th of May based upon my ovulation date! (I ovulate late). My OB does ultrasounds at 5 weeks for dating purposes but at 5 weeks 2 days, all they could see is a yolk sac & a gestational sac. I try not to worry because I know I'm SUPER early but this is my first pregnancy and every little thing is new & scary to me!
