Stages of pregnancy
Pregnancy week
12 Weeks pregnant - What to expect ?
At 12 weeks pregnant, you’re reaching the end of your 1st trimester—a phase many women find the most challenging. This week brings noticeable physical, emotional, and developmental milestones for both you and your baby.
Your Physical Changes This Week
- The skin around your nipples may become darker; pigmentation patches may appear on your face.
- A dark vertical line (linea nigra) may start forming from your navel to your pubic area.
- Nausea and fatigue begin to fade, bringing more energy.
- Increased blood volume may give you the famous pregnancy "glow."
- Pimples may reduce, revealing a clearer complexion.
- Frequent urination decreases as the uterus lifts and gives your bladder more space.
- You may feel the top of your uterus just above the pubic bone when lying on your back with a full bladder.
Your Emotional Changes This Week
- You may feel euphoric as energy returns and queasiness reduces.
- Many couples choose this time to announce pregnancy because miscarriage risk drops.
- You may still feel sensitive or tearful—crying helps release emotions.

- Sex is safe unless at risk of premature labour or if membranes have ruptured.
