Week 13: First Trimester Complete
Transition week — energy returns, appetite stabilizes
You made it through the first trimester. Her nausea should be fading, energy levels improving, and appetite returning. This is the bridge week between surviving and actually enjoying the pregnancy. The second trimester — often called the 'golden trimester' — starts next week.
What's happening this week
The fetus can swallow and produce urine. Vocal cords are forming. Intestines have moved from the umbilical cord into the abdomen. The body is starting to catch up to the head in size. Her uterus is now large enough to rise out of the pelvis.
Your checklist
0 of 4 completeIf you did any first-trimester screening (NIPT, NT scan, combined screening), all results should be in by now. Make sure you've discussed everything with your OB and have a clear picture going forward.
You don't need to buy anything yet, but start thinking about the room — what needs to move out, what color you want, what furniture you need. Pinterest boards are fine. Action comes later.
Most birthing classes are taken in the third trimester but popular ones fill up months in advance. Start researching options — hospital-based, independent, online (Lamaze, Bradley Method, etc.).
Baby costs add up fast. Start thinking about your monthly budget post-baby: diapers (~$70–100/mo), formula if needed (~$150–200/mo), childcare ($800–$2,500+/mo depending on location). Build these into your financial plan now.

Completing the first trimester is a relief for most expecting parents. The highest-risk period is behind you, morning sickness is typically fading, and you can finally start sharing the news and planning ahead without the cloud of early pregnancy anxiety.
For dads, week 13 is a good reset point. The survival mode of the first trimester — managing nausea, keeping secrets, processing screening results — gives way to the more proactive second trimester. This is when you shift from reacting to planning: nursery setup, financial adjustments, birthing class research, and baby registry building all start in earnest over the next few weeks.
