Where You Are in the Timeline
Weeks, trimesters, due date — and how months translate into weeks, which nobody explains clearly.
From working out your due date to packing the hospital bag: practical guides for getting through pregnancy with fewer 2 a.m. searches — and, when the time comes, a free registry to build.
Weeks, trimesters, due date — and how months translate into weeks, which nobody explains clearly.
Small miseries and big worries, and what actually helps.
The last stretch: what to organize, and when.
If a baby shower is coming, this is when the registry needs to exist — the link usually goes out with the invitations.
The standard method adds 280 days — 40 weeks — to the first day of your last period. A first-trimester ultrasound refines it against how the baby is actually measuring, and that estimate wins if the two disagree.
Most people start between weeks 28 and 32, so the class finishes with a few weeks to spare. Book earlier than that: the good ones fill up.
Photo ID and your insurance card, prenatal records, a change of clothes for you and the baby, toiletries, long phone charger, going-home outfits. A full checklist is the difference between packing once and repacking at 3 a.m.
Most families build it in the late second or early third trimester. That leaves time for the long-lead items — stroller, car seat, crib — and gets the link ready before the shower invitations go out.
