Your First Trimester, Week-by-Week

Week 4
Positive test: You're pregnant! You may be starting to feel bloated, crampy, tired and moody, and experiencing sore breasts, nausea/vomiting and a frequent need to pee. But don't worry if you're not, that's normal.

What to do now:

  • Invest in an extra supportive bra, especially if your breasts are expanding. Many women grow a full cup size in the first few weeks.

  • Avoid chemicals and secondhand smoke. Ask your partner to take over the litterbox duties (cat feces may harbor parasites that cause toxoplasmosis, an infection that can harm the fetus) and to pump the gas in your car.
