But doesn’t the 9 months of pregnancy technically start on the first day since a woman’s last period? That’s what makes anti-abortion laws even more absurd, because you can be 8 weeks pregnant if you only had sex 5 weeks ago.

I thought it was 9 months from the first missed period

  Lol had to look this up because it’s complicated.

  “Ovulation [when an egg is released from your ovaries ready for fertilization] typically takes place around two weeks after the first day of your last period, and this is when a baby would be conceived. But because you won’t know that you’re pregnant until you’ve missed your next period, approximately two weeks later, you’ll already be four weeks pregnant when you get your positive test result. At that point, you’ll have approximately 36 more weeks to go,” Dr. Celestine says.
  
  So pregnancies typically last 10 months, but we say 9 months since you don’t even know you’re pregnant until you’re 4 weeks pregnant. But anti-abortion laws still count that 4 weeks.

    By that logic conception only occurs when you’re two weeks pregnant. That’s an extremely silly way to count it. (Not saying you’re wrong, just that it’s frustrating.)
