I think what I meant to get at was when people identify the first few weeks as OK for abortion. Say, what if someone says the blastocyst is just “a clump of cells”?
You realize the blastocyst cycles lasts from about 5-6 days post-fertilization until implantation, which is around Day 11-12.
None of us knows when conception happens— sperm can live for about five days in the reproductive tract-- but I generally knew I was pregnant within 3 days of DTD. Waiting a week or two after your first missed period for a pregnancy test for detectable levels of hCG in your urine— it’s just confirming what you already know. Because, if you’re in tune with your body, “Ohmigosh, I’m pregnant” is way different from “Yeah, my period is missed or late, but I know I’m not pregnant. My cycle is just out of whack.” But a lot of women are so hopped up on hormones in birth control pills— I’m not surprised they’re out-of-touch with being able to instinctively realize they’ve conceived, even prior to implantation, even if they’ve never been pregnant before in their lives. You just know.
But the point being, most people who want to abort a blastocyst because it’s “just a clump of cells”— are likely not going to realize they’ve conceived before the baby has moved on from the blastocyst stage to the embryonic stage (which begins with implantation, and lasts about four or five weeks, which is six weeks post-conception).
However, the people who do believe that blastocysts are just a clump of cells are going to be the ones who are okay with birth control. (Or, the ones who support birth control will be the ones who don’t understand how it works. It’s not a magic pill that mysteriously kills all sperm, or gives your ova an impenetrable coating.) Because one of the things birth control does is prevents the blastocyst from implanting. So you lose your child— and you might never know you had one.
But the “blastocysts are people, too” argument is going to be an argument where you go, “OK, now that we understand that abortion is wrong, this is why birth control is wrong.” But right now, we’re trying to make up lost ground and get everyone on the same page to agree, “Killing your 8-week-old baby is just as wrong as killing your 38-week-old baby is just as wrong as killing your 68-week-old baby.”
