Developments this week
Hello, wiggles. Your baby’s arms and legs finally have the muscle to pack a punch (or a kick). Those early flutters might graduate to proper jabs this week, especially when you’re sitting still.
Little ears tuning in. Sound travels well in there now. Baby may react to loud noises, yawning or jumping at sudden sounds. Chatting or playing music creates their first sense of your voice.
- Vernix at work. That creamy coating on baby’s skin? It’s protecting their delicate skin from all that amniotic fluid.
- Practice breathing. Tiny chest movements mimic breathing, no air yet, but key muscle training.
- Hair sprouts. Scalp follicles start producing actual hair (lanugo) this week. Color comes later.
Your uterus is just below your belly button now, which explains why waistbands feel impossible. Time to embrace the stretchy pants (no shame).
Odd cravings don’t always mean nutritional needs. Wanting pickles at 2 a.m.? Probably just hormones. But if you’re suddenly repulsed by former favorites (coffee, meat), find swaps that work.
Body changes & red flags
Round ligament pain. A sharp tug low in your belly? That's likely these bands stretching to support your growing uterus. Moving slowly (especially when rolling over) helps.
- Lightheadedness. More blood volume + wonky blood pressure can make you feel dizzy fast. Sit down if you're feeling fuzzy, and don't skip snacks.
- Nasal congestion. Pregnancy hormones swell mucus membranes. A humidifier or saline spray might help you sleep easier.
- Crazy dreams. Vivid, sometimes unsettling ones are common now. Blame the hormonal whirlwind (and maybe that taco before bed).
Pelvic pressure is normal, but mention any severe pain or cramping to your provider. Same goes for bleeding, even light spotting deserves a quick check-in.
Appointments & milestones
The big anatomy scan (if you haven’t had it yet)
Scheduled between 18–22 weeks, this ultrasound checks baby’s organs, limbs, and growth. You’ll likely see tiny fingers waving, maybe even a thumb-suck. (Bonus: This is often when the sex becomes obvious, if you’re finding out.)
- Drink water before your scan, a full bladder helps the images.
- Ask about video or photos. Many clinics offer keepsakes now.
No two babies pose the same for the scan. Some show off, some hide.
