Your pregnancy at 7 weeks
What's happening with mum
While you may be lucky enough to miss out on morning sickness you may still find yourself nauseated by certain smells. The hormone estrogen, which is paying a big part in helping the devlopment of your baby, is also heightening your senses, particularly smell. Sometimes even your favourite smells can become overpowering. Try to find some soothing scents, change your shampoo, body lotion etc. to something neutral with no perfume and regularly change your bedding to try to alleviate those stomach churning odours.
If you find you can't venture out or go to bed without worrying about the need to pee you should try to avoid drinks containing caffeine. While the jury is still out on whether it increases the need to pee because of it's diuretic properties, it is a stimulant and will hamper your ability to relax.
While you may not be able to see your bump yet, your weight may fluctuate up or down and while small increases or decreases are normal, if you experience a sudden gain or loss you should consult your doctor.
What's happening with baby
At this stage baby should measure approximately 5 to 12mm and is really starting to develop. Externally those little lumps and dents are now becoming facial features such as jaw and mouth and even eyelids should be forming this week. Internally the organ continue to develop with the liver beinning the production of red blood cells and the appenix and pancreas beginning to form. The pancreas will play an important role in digestion by producing the insulin hormone.
While it is still too early to tell whether you baby is a boy or a girl, the sex glands will also start to form this week.
This week is considered the ideal time to arrange for your first ultrasound scan. This will most likely be a transvaginal ultrasound during which time the technician will insert a small lubriated probe into your vagina. This probe uses sound waves to create an image of your baby in orer to check the baby's heartbeat and the health and position of the placenta.
