Big Fraternal Twins?

Hey ladies I'm 30 weeks pregnant with my boy girl twins. At my last scan at 27 weeks baby boy was already measuring 2 pounds 11 ounces which the dr said he is a big boy and my little girl was measuring bigger to. They are also very long due to me and my husband being tall. I'm 5"10 he's 6"2. The closer I get to my due date the more uncomfortable I am really becoming. I know it contributes to them being big ! We know our dates are correct due to us conceiving from ivf. Do you think I will deliver early ? I mean of course I want them to be nice and healthy so I worry but I also don't want to birth two 9 pounders lol. I go for another growth scan at my high risk dr on Tuesday and I'm e cited to see how much more they have grown in a month. I am high risk due to twins, ivf, tachycardia and hypothyroidism. I am also having a ton on pressure in my crotch due to baby boy head and his being so heavy. Can any of you relate to this ? Thank you !:)
