Possibly big/long baby

Nola • Feb 2019 💙👣

So I went to my first appointment a few weeks ago, my app stated I was 7w4d but my Dr measured me at 8w1...The father is tall maybe 6’3/6’4 and I’m only funsize 5’3, I’m going to ask my Dr about this next week at my “11w” appointment about the difference in dates...but could I just be having a long baby lol oh my child’s father has a two year old son which is half my size already
