Learn what to expect throughout pregnancy from the first weeks to the final months and how to prepare for delivery at The Mother Baby Center.

The time of pregnancy is calculated from the first day of your last menstrual period (LMP), which is typically two weeks before conception actually occurs. This means the first two weeks of the 40-week count are before fertilization, during which your body prepares for ovulation and a new cycle begins

    Oh, I get that. The point is that it doesn’t really make a difference for the woman or the healthcare delivery if it’s out be a few days due to sperm migration or being unsure which activity caused conception to occur.

    However, it makes sense from a biological point of view to track the full pregnancy. From egg release onwards. Without egg release, there is no pregnancy. Without fertilization, there is no pregnancy.

    It also makes sense to have it be standardized across disciplines. There is no logical reason to change it from its current definition. It’s not perfect currently, being an estimate, but it’s the closest we have.

    However, what is importtfrom a reproductive rights point of view is for people to understand how little time there is to make a giant decision about whether to abort or keep the baby. Often there is just a 2 week window, which in that time there needs to be a doctor’s consult and a procedure scheduled, irrespective of work, family, health, study or other commitments. When people hear 6 weeks, they think that’s a reasonable time frame to make a big decision and arrange it. When it drops to 2, that’s different.
