Your baby this week
Big news this week — your baby's heart is beating! About 100-160 times every minute, and if you get an ultrasound, you might actually hear it. Your baby is the size of a lentil and curved like a tiny C. Little buds are appearing where the arms and legs will be. The eyes and ears are starting to form, and the digestive system is beginning to develop. There's still a little tail — but don't worry, it will go away soon.
Your body this week
Nausea and fatigue are probably intensifying. You may find certain foods revolting while craving others — your body is calling the shots right now. Mood swings are common as hormones fluctuate wildly. Bloating and constipation may appear, thanks to progesterone slowing your digestion. On the bright side — if you have an ultrasound this week, you might see or hear your baby's heartbeat for the very first time. There's nothing quite like that moment.

Every pregnancy is different — you may notice some of these, all of them, or none at all. None of this is a checklist to worry over.
