Pregnancy week 7 is a time when baby’s organs develop rapidly and mums are like to experience pregnancy symptoms like morning sickness.
Changes for mum
- A thick layer of mucous which blocks the entrance to your womb develops this week. It’s called the cervical plug and protects your baby from foreign substances throughout the pregnancy.
- Pregnancy hormones are hard at work and most women experience pregnancy symptoms as a result of the hormonal changes.
- Morning sickness is the most common pregnancy symptom. It’s unpleasant but unless very severe it’s nothing to worry about.
- It’s also common to feel tired or emotional at this stage of pregnancy.
- You may notice your breasts changing and they may be sore or tender this week.
Changes for baby
