Welcome to week 15 of your pregnancy! This week, your baby is as big as a grapefruit. Here’s what else you can expect this week.

Hopefully morning sickness has shuffled off for good now, but if not, speak to your GP or obstetrician about potentially taking some anti-nausea medication if needs be. You may start noticing a small baby bump, which is an exciting milestone.

Anything else?

If you’ve got any bit of a bump now, buying some maternity clothing might be necessary. No one will judge you if you live your life in comfy leggings for the next few months as your body changes. You might notice that you have swollen gums that are prone to bleeding when you brush or floss. It’s those pregnancy hormones again, pesky little blighters, triggering gingivitis and causing gum inflammation. Yay!

Enjoy all the benefits that come from being ‘with child’; skipping the line for the bathroom, strangers smiling at you, getting to name a human, and best of all – naps.
