Gender ultrasounds done earlier than they were 2 years ago?

With both my boys, born 2012 and 2013, I think it was standard to wait until, at the earliest, 18 weeks for gender scan... Is that different now or was I behind the times? I have always done midwife care, so maybe that's why? Anyone else who's had previous pregnancy feeling like "how are all these women finding out the gender at 15 weeks???" Also if I can find out sooner, I'd love to! Hoping if this is the new standard that my midwife is with the times 😉
