@Jens_Rasmussen @merchantHelios Hormones are a lot more complex than an on-off switch. Lactation doesn’t happen ‘til later anyway.
IIRC it uses something like FSH to signal to the ovaries that there’s an egg implanted in the uterine lining so they don’t release one on the monthly cycle, at least the oldest banner med was. Lots of mechanisms to count.
It’s like making the body constantly think it’s in the first 3 weeks of pregnancy all the time.
