Twins/plus sized?'

Kendra • Happily Married!! Two beautiful little girls :)
Anyone else notice more plus sized women have twins?! Or is it just me. My daughter was a twin ( I lost her twin at 8 weeks) and now I'm pregnant again and wondering if it may be twins? I'm 6w1d and don't get a ultrasound till after 8 weeks. Also I lost over 20 pounds my last pregnancy. Anyone else? My OB said it was normal. To bad I gained it back after he was born lol. Congrats ladies!
