shoulda asked 🤷🏻‍♀️

So my second appointment at. 10 weeks and 2 days they took A LOT of blood work I think it was 8 tubes . Idk why I didn't ask lol but I was wondering obviously no one will really know but "usually" what do they take blood for ? She had asked me before all this when getting my weight if me or my bf had anyone in the family with autism . So maybe that? Is that how you check. I'm sorry I'm super naive this is my first pregnancy all I wanted was for the needle to be out and get out of there 😂. So if anyone has any clue thank you in advance 😊
