Try Guix instead :)

Big, welcoming community; Fully libre distribution; Time-tested Scheme (Guile) instead of that stupid nix stuff.

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.

There's a big peak around Christmas due to Easter, which sucks, because while there's a peak, fewer midwives are available because they too have more time off around christmas.

Don't get pregnant during easter!
