Hyundai Genesis. Hyundai Genesis. Striking the right balance of design, luxury, and performance, the Genesis represents a lot of car for the money. Under the hood is a 311-hp V-6 with rear-wheel drive; all-wheel drive is optional. If you want more performance, a 420-hp V-8 with rear-drive is available; an eight-speed automatic is standard on all.
You should be able to find out whether you're having identical twins during a first trimester ultrasound scan. Before 14 weeks, it's easier to see on a scan whether your babies each have their own placentas and membranes (NCCWCH 2011, NICE 2011, RCOG 2008).
That being said, it IS possible to miss a twin for awhile. There was a girl here or on r/cautiousbb who found a twin at 21 weeks during her anatomy scan. Rare, but could happen. Bring your concerns up to your doctor but truthfully, I feel if they haven't seen 2 babies by the time your second trimester starts, you're probably just having one.
