Gentetic testing?

So I am 11w6d pregnant with my first baby. I’ve had two appointments with my doctor already and she did an ultrasound with both, one at roughly 7 wks and 10wks and both she said were normal. If it wasn’t for everyone on here, I’d have no idea about the blood testing for the generic abnormalities and to find out the gender even. I find it weird she hasn’t mentioned this to me at all, I have another appointment at the end of the month, is it worth mentioning? Also I’ve noticed most don’t have their first ultrasound until at least the 11ish week, and I’ve already had two, does anyone find this odd, do you suppose it’s just physician preference? Is it normal? I have so many questions and no one to ask lol

Thanks!
