On avrage a woman’s menstrual cycle is 28 days. 6x7=42. Given that a woman can’t get pregnant until around day 14, a woman would definitely miss 1 period and probably 2. Do we need to explain how babies are made too? Maybe that’s the disconnect here.
Yikes. The only display of disconnect here is your shocking level of ignorance about the female body, once again proving that anti-abortionists have no clue about how pregnancy works or what their preferred legislation actually means in reality.
It is medically ignorant and inaccurate to assume every cycle is 28 days and even rather outdated. It is only just an average, not a standard; cycles vary between individuals and even month to month for the same person. Irregularities are common, and treating them like exceptions instead of the norm is just bad science. But, it is not like science has ever been your camp's starting point, so it is not surprising to see you make these claims.
The way in which you are measuring pregnancy is also inaccurate. It is not counted from conception, it is from the first day of the last menstrual period. That means someone who’s “six weeks pregnant” probably conceived only 2–3 weeks ago. So if she has a "regular" cycle, she might just now realize her period is late. And even that assumes she has symptoms, a predictable cycle, and access to a test. Many early symptoms feel like PMS too, so by the time someone buys a test and confirms they are pregnant, the legal window may already be closed. There is no magical “2–3 week free pass.” A six-week limit is, in practice, a total ban.
Not too forget the most cruel part of this, you are ignoring those hit the hardest, namely the young girls. A 13-year-old is not tracking ovulation. She might not even yet understand what is happening to her body yet. She cannot realistically be expected to recognize and process a pregnancy in time to meet your arbitrary legal deadline. So she will be forced into motherhood while she’s still a child herself.
