Congratulations! Your missed period this week may be the first sign that you’re pregnant. You may also be starting to feel pregnant because of pregnancy symptoms like morning sickness, heartburn and insomnia. Breast and cervical changes which occur in early pregnancy may also be signs that you’re pregnant. Find out more about what to expect when you’re 5 weeks pregnant.
