Pregnancy weeks 14 to 16 marks the beginning of the second trimester of the pregnancy. Pregnancy weeks 14 to 16 show major changes with the developing and growth of the foetus. The weekly pregnancy calendar will detail every little change during pregnancy weeks 14 to 16 so that you can follow the weekly changes of your baby throughout weeks 14 to 16 of your pregnancy.
Pregnancy Week 14

Pregnancy Week 14 is the starting of the second trimester of pregnancy, which is the second three-monthly stage of being pregnant. The new lease of energy and happiness will improve in week 14 of pregnancy and should give you a glow to your skin and a bounce in your step.
Sudden nosebleeds or gums bleeding when brushing teeth may continue this week as the changes to the level of the hormone progesterone is still taking place in the placenta.
Clothing around the waistline may still be a little restrictive and the need to loosen clothing as the stomach tightens up may be a wise choice for your own comfort. Little body shape changes will be more noticeable to you and the feeling of being fat is normal as an expectant mothers during week 14 of your pregnancy.
In the 14th week of pregnancy it is possible that you may notice the baby moving around within your tummy and this should feel like small flutters.
Foetal Development at 98 Days Pregnant
The foetus should weigh approximately 55 grams now and will be measured around 9cm in length due to more rapid growth.
The rapid growth of the foetus will become more evident from week to week now as the major developments of organs etc have taken place and the advanced growth is due. The head of the foetus will continue to grow that little bit more than the rest of the body of the foetus. The midwife upon examination of your tummy will have no difficulty finding the fundus when feeing your tummy, the fundus is the medical term for the top of the uterus.
The foetus will now have fully developed the gag reflex and growth of the nasal passages at week 14 of pregnancy are almost completed.
The bowels are fully advanced now, but the meconium will still be produced in the bowels as tiny amounts. Meconium is the bowel movement producing faeces.
Ossification of the bones of the foetus is an on going process. Ossification means that the soft cartilage bones are growing harder and stronger from the centre.
Ultrasound at 14 Weeks Pregnant
The crown to rump length of the foetus is about 8 – 9cm in length at 14 weeks pregnant.
The doppler device will almost certainly be used to measure and monitor the heartbeat of the baby with much clearer results at 14 weeks pregnant.
Pregnancy Week 15

During pregnancy week 15 the experience should be plain sailing now as the energy that you once lacked is now fully restored, and then some.
The sudden nosebleeds or gums bleeding when brushing teeth should start to subside this week as the changes to the level of the hormone progesterone are almost complete in the placenta.
Clothing may still need to be loosened for comfort and ease of mobility. The feelings of being fat should also start to subside now as you are more aware that you are with child due to the fluttering sensations in your tummy.
Although some people say that it is not possible until weeks 18 – 22 of pregnancy to feel the baby, I disagree, it is still very possible to feel the foetus in the 15th week of pregnancy, however small the flutters of the baby are.
Foetal Development at 105 Days Pregnant
The foetus will probably now weigh approximately 90 grams now and should measure up to and around 12cm in length as the growth is happening constantly.
The rapid growth of the foetus is on going and the head of the foetus should still be growing faster than the rest of the body. During examination at pregnancy week 15 your midwife should be able to locate and find the fundus (top of the uterus) almost halfway between the naval and pelvic bone.
The umbilical cord has started its formation during week 15 of pregnancy. The umbilical cord consists of one vein and two arteries wrapped up in a tough jelly like substance often referred to as Whartons Jelly.
The amniotic fluid fills up around the foetus allowing freedom and comfort to float around and most importantly stretch out and wriggle.
The foetus is becoming able to make and form facial expressions due to the formation of the vocal chords, this can be noticed on ultrasound scans if the foetus is looking in the correct direction.
Tiny hands and fingers can now stretch out and grasp around them, do not be alarmed if your baby wants to explore you properly, their tiny fingers can feel around the uterus and should you gently press your tummy then you can communicate with your fifteen week old baby, thoroughly amazing concept, but do remember to be gentle.
Ultrasound at 15 Weeks Pregnant
The crown to rump length of the foetus will now be around 9cm in length during pregnancy week 15.
The doppler device will be used to measure and monitor the heartbeat of the baby with much more clearly defined results at this stage of pregnancy.
Pregnancy Week 16

Pregnancy Week 16, by now you should be fully aware that you are expecting a baby and relish the thought of the tiny life growing inside of your tummy.
The sudden nosebleeds or gums bleeding when brushing teeth should have stopped as the levels of the hormone progesterone should have levelled out within the body now.
Common sense and consideration should be applied when selecting clothing, tight is uncomfortable and looser is better. The feelings of being fat should be replaced with full awareness of your pregnancy as the sensations and flutters in your tummy provide gentle reassurance.
Some people still say that it isn’t possible to feel the baby until weeks 18 – 22 of pregnancy, I strongly disagree with that statement as every expectant mother is unique in this sense and the very possibility of detecting the foetus in the 16th week of pregnancy is common here in the UK, no matter how tiny sensations happen to be.
Foetal Development at 112 Days Pregnant
The foetus should be weighing almost 120 grams by now and the measurements could well be up to a good 15cm in length now.
The continuing growth of the foetus should now mean that head of the foetus is almost a third larger than the size of the body.
The midwife should be able to locate with ease the fundus (top of the uterus), which is now halfway between the naval and pelvic bone.
The umbilical cord has now fully formed. The umbilical cord consists of one vein and two arteries wrapped up in a tough jelly like substance often referred to as Whartons Jelly.
The amniotic fluid continues to slowly surround the foetus allowing agility whilst he or she can explore their sensory environment, again the importance of being unrestricted must be relaxing for the foetus.
The foetus can probably now form one or two different facial expressions as the formation of the vocal chords are near to completion during week 16 of pregnancy.
As well as having the ability to stretch out tiny fingers and grasp with their hands, the baby can now suck at their thumbs and fingers in between their exploration of your uterus. It has been known before that babies can be caught sucking fingers and thumbs during ultrasound scans, which can be amusing.
Ultrasound at 16 Weeks Pregnant

The developmental growth of the foetus shows massive changes on this ultrasound scan at 16 weeks of pregnancy.
The measurements of the crown to rump length of the foetus could be as much as 10cm in length when you are 16 weeks pregnant.
The doppler device will be used during visits to the doctors to monitor the heartbeat of the unborn baby with clearly defined results at this stage, week 16 of pregnancy.
