First Trimester: Week 1-6

The first two weeks of pregnancy are a bit of a misnomer, because you are not actually pregnant – yet! It’s not until approximately week three when conception finally occurs and that magic moment when sperm and egg fuse (otherwise known as fertilisation) results in a zygote, a single-cell organism made up of genetic material from both you and your partner.

The fertilised egg (aka your baby!) contains 46 chromosomes – 23 from you, 23 from the father. The mother always provides an X chromosome. The father can provide an X or Y chromosome. If the sperm that fertilises your egg carries an X chromosome, the XX zygote will be a girl. If the sperm is Y-bearing, then your XY zygote will be a boy.

Remarkably, within hours, the single-cell zygote divides, and then each cell divides again. Within days, you’re walking around with a microscopic ball of cells (now known as a blastocyst) and it’s now making the journey from your fallopian tube to your uterus where it will implant and settle for the next nine months!

When you become pregnant, be prepared for the flood of advice that will bombard you (another good reason to limit who you tell until you can’t hide it any longer!). Eat right, exercise, do this, avoid that. None of us is perfect—everyone has a habit or two they need to break or something they could do better. For many women, pregnancy is a great motivator to make some permanent changes. Whether it’s quitting smoking, exercising more, changing your diet or reducing your stress level, one piece of great advice fits every situation: don’t go it alone. Enlist the help and support of your friends and family. Find a walking partner, share healthy recipes with your friends, join a prenatal yoga class or ask someone who successfully quit smoking what worked for them. Building your circle of support now will help you throughout pregnancy—and beyond.

Something you might not think of as a priority just yet, but which will have major implications on your pregnancy care and birth is choosing a caregiver and a birth setting (the two usually go hand in hand). These are two of the most important decisions you will make in pregnancy. They profoundly influence the path of your pregnancy, birth and early mothering. You may not realise all of the options you have. If you are healthy, you can select either a midwife or a physician to provide your care. You can consider birthing in a hospital, a birth centre or at home. Checking into your options early in pregnancy will enable you to make the best decisions for you.

Jolene enjoys writing, sharing and connecting with other like-minded women online – it also gives her the perfect excuse to ignore Mount-Washmore until it threatens to bury her family in an avalanche of Skylander T-shirts and Frozen Pyjama pants. (No one ever knows where the matching top is!) Likes: Reading, cooking, sketching, dancing (preferably with a Sav Blanc in one hand), social media, and sitting down on a toilet seat that one of her children hasn’t dripped, splashed or sprayed on. Dislikes: Writing pretentious crap about herself in online bio’s and refereeing arguments amongst her offspring.
