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).
And as far as a test goes, I did test positive at 11dpo, but I don't know if having twins had anything to go with it. I found out by u/s at 6 weeks. I think 5-6 weeks is the earliest you can really know by u/s. As far as other ways, my hCG didn't really lead me to believe twins. It was 77 at 12dpo, then 1489 one week later... so pretty on par with doubling every 48 hours.
