Your baby at 12 weeks
Just 12 weeks after your last period, the foetus is fully formed. All the organs, muscles, limbs and bones are in place, and the sex organs are well developed. From now on, the baby has to grow and mature. It’s too early for you to be able to feel the baby’s movements yet, although they’ll be moving quite a bit.
You at 12 weeks
You might notice you’re a bit constipated. Not everyone gets constipation in pregnancy, but it’s fairly common and can make you feel uncomfortable. You may feel stomach pain or cramps from time to time. These are usually nothing to worry about, and can be caused by constipation, wind or your ligaments growing as your womb gets bigger. But if you have stomach pain that does not go away, is severe or you also have bleeding or other symptoms, you need to see your midwife or doctor.
